Superconducting quantum computing is that the formation of quantum computers using the superconducting electronic circuits.

These circuits have zero electric resistance, thus they are 60 to 100 times more energy-efficient than today’s chips. these chips also have a higher amount of processing power, the superconducting-chip that use so-called Josephson junctions have been clocked at 770 gigahertz. These are using Qubits in a superconductive state , thus they are much secure th an the traditional chips.

**Quantum annealing** is a higher-level procedure for finding the global minimum of the given objective function over a given set of candidate states. It is used widely for combinatorial optimization problems with many local minima. The procedure utilizes the quantum fluctuations to solve the problems having a discrete search space.

Quantum annealing which is also known as tempering or crystallization is analogous to simulated annealing, but in substitution of thermal activation by quantum tunneling.

**Quantum dots** are a few nanometers sized semiconductor particles having both optical and electronic properties. When the dots are illuminated by the UV rays, an electron can be excited to a state of higher energy.

Quantum dots are even referred to as "artificial atoms" having discrete electronic states and emphasizing their singularity. Quantum dots have the properties intermediate between bulk semiconductors and discrete atoms.

Some of the potential applications of the quantum dot are including solar cells, LEDs, quantum computing and medical imaging.

**Quantum Thermodynamics** addresses the continuous dialogue between Thermodynamics and Quantum mechanics. The 4 laws of thermodynamics are presented as a quantum consideration.

Classical Thermodynamics is a theory of large scale macroscopic processes. Whereas quantum theory on a probabilistic footing relevant for a single particle. Thus quantum mechanics allows thermo dynamical concepts to be applicable on any scale.

**Post-quantum cryptography** better described as a public key safeguard against any attack from a quantum computer. Because a forecast shows that, most of the public keys can be easily broken by a strong quantum computer. Again the reason behind it lies in the problems; those are given by a traditional public key, like the integer factorization or discrete logarithm or the elliptic-curve discrete logarithm problem.

The above problems can be easily solved by a strong quantum computer running Shor’s algorithm. It is considered that the hash function and the symmetric cryptographic algorithms are relatively secure against an attack by a quantum computer.

Post-quantum cryptography is the attempt to develop new kinds of cryptographic approaches and solutions that can be implemented using today’s classical computers but will help to protect the anonymous attacks from tomorrow’s quantum qubit computers.

Any new cryptography has to integrate with existing protocols, such as TLS. A new cryptosystem must weigh:

- The size of encryption keys and signatures
- The time required to encrypt and decrypt on each end of a communication channel, or to sign messages and verify signatures, and
- The amount of traffic sent over the wire required to complete encryption or decryption or transmit a signature for each proposed alternative.

Creating an interface, where data encoded in light, quantum devices that contain multiple optical spectra would share and process the data in a quantum network is called **quantum light interface**.

One must thing required for this type of networking would be the scalability that says, the ability to drive the input of a node using the output of another node.

Quantum light-matter interface is so useful in quantum computing, quantum communications and quantum sensing.

This includes from single-photon sources for quantum communication to quantum memories for wavelength conversion.

The protocols have been successfully demonstrated and for further increase in performance, a deeper understanding of the relevant noise and decoherence processes needs to be gained.

**Quantum magnets** are spin systems in which the spins interact via the well-known exchange interaction. The interaction is purely quantum mechanical in nature.

We can demonstrate the quantum fluctuations and compete for interaction in the quantum magnetism. Quantum magnetism could be a bit totally different from classical magnetism, the sort you see after you stick a magnet to a refrigerator, because the individual atoms have a property known as spin, which is distinct states (usually known as up or down). Seeing the behavior of individual atoms has been hard to do, though, as a result of it needed cooling atoms to very cold temperatures and finding a way, how to “trap” them.

**Quantum field theory** is the conceptual framework that combines the classical field theory, special relativity, and quantum mechanics and then it creates physical models of subatomic particles and quasiparticles in particle and condenses matter physics respectively. This theory treats particles as excited states of their corresponding underlying fields.

One of the demonstrative tools of quantum field theories is quantum electrodynamics, which provides a conceptual mathematical platform for predicting and understanding the effects of electromagnetism on the electrically charged matter at its all energy levels. Electric and magnetic forces are regarded as arising from the emission and absorption of exchange particles called photons.

**Spintronics** is the best known as spin electronics. Quantum spintronics is different in the property from traditional electronics. In addition to charge state, electron spins are exploited as a further degree of freedom, thus gives us better storage and transferring facility of data.

Spintronic systems are most often found in dilute magnetic semiconductors (DMS) and Heusler alloys and are very useful for the next quantum technology that enables us the ultra-quantum computing.

Spin transport electronics can have revolutionized traditional electronic devices as never before, especially when it comes to computing. While standard electronics use an electron's charge to encode information, spintronic devices rely on spin, which much more power-efficient than it consumes today.

The most complex question plaguing is how the signal carried by particles with spin, known as spin current, decays over time!

**Quantum Information Processing and computing **derives the processing of data and therefore computing based on quantum mechanics. The traditional computers we use usually process the input using the binary digits called as bits like 0 and 1, but the quantum computer performs the tasks using the quantum bits called as Qubits, which exists in a superposition state of an atom. Qubits can be implemented with atoms, ions, photons or electrons in a suitable environment that work together to act as a smart processor. Due to the spin of the electron in the atom, a quantum computer can contain multiple states simultaneously, hence they provide inherent parallelism. This technique will open the opportunity to solve much bigger and complex problems in much lesser time than a traditional computer. Here is the long way ahead with genuine quantum effects such as superposition and entanglement.

**Quantum chromodynamics** is that the concept of the strong interaction between quarks and gluons, the basic particles that form up composite hadrons i.e. the proton, neutron and pion. QCD is a kind of quantum field theory known as a non-abelian gauge theory, with symmetry cluster SU(3). The quantum chromodynamics analog of electric charge is a property known as **color**. Gluons are the force carrier of the idea like photons are for the electromagnetic force in quantum electrodynamics. The theory is a vital part of the quality Model of particle physics.

QCD exhibits two main properties:

- Color confinement-This is a consequence of the constant force between two color charges as they are separated: To increase the separation between two quarks within a hadron, ever-increasing amounts of energy are required. Eventually, this energy produces a quark-antiquark combination, turning the initial hadron into a pair of hadrons instead of producing an isolated color charge. Although analytically unproven, color confinement is well established from lattice QCD calculations and decades of experiments.
- Asymptotic freedom - a gentle reduction between the strength of interactions between quarks and gluons as the energy scale of these interactions increases (and the corresponding length scale decreases).

**Quantum** **simulators** allow the study of quantum systems that area unit troublesome to review within the laboratory and impossible to model with a mainframe supercomputer. In this instance, simulators are special-purpose devices designed to provide insight into specific physics problems. Quantum simulators may be contrasted with generally programmable "digital" quantum computers, which would be capable of resolving a wider category of quantum issues.

**Quantum communication** is another field of applied quantum physics related to quantum information processing and quantum teleportation. It is the most fascinating application is protective data channels against eavesdropping by mean that of quantum cryptography.

Quantum communication takes advantage of the laws of quantum physics to shield the information that will process or transmit through the technology. These laws allow particles—typically photons of light for transmitting data along with optical cables to take on the state of superposition, which means they'll represent multiple combos of one and zero at the same time. Those are known as Qubits. The principle advantage of qubits from a cyber-security perspective is that if a hacker tries to observe them in transit, their super-fragile quantum state collapses to either 1 or 0. This means a hacker can’t tamper with the qubits while not let go of a telltale sign of the activity.

**Quantum Tunneling** is the phenomenon of quantum mechanics that describes the surmounting of subatomic particles through a potential barrier. It plays a vital role in the phenomena like a nuclear fusion in the sun, quantum computing and scanning the tunnelling microscope. Tunnelling can be explained as the quantum object can be known as a wave or as a particle in general. In this phenomenon, the quantum or the subatomic particles borrow energy from the surrounding to penetrate the potential barrier and hence the phenomenon cannot be explained by the classical mechanics. The phenomenon is giving a high value to quantum computing as it has the potential to optimize the energy consumption and the efficiency of a processor.

**Quantum paradox** is a thought experiment conducted by the great scientist Albert Einstein that shows the unavailability of the complete information in a wave function. Hence the Copenhagen interpretation is unsatisfactory. Again resolutions of the paradox have great applications in interpretation in Quantum Mechanics. The concept was to predict both the position and the momentum of the wave-particle at the same time and more accurately. It also describes that the information would go faster than light if we would try to measure the one particle though it is forbidden in the theory of relativity because measuring one particle would affect the other to prevent the accuracy and that involves the wrong phenomena that, information transfers faster than light.

Today this paradox phenomenon is involved in Quantum Entanglement which describes that when the groups of particles are gathered or interact with each other, then the quantum state of an independent particle cannot be described. Hence EPR paradox has a measure role in quantum technology.
