1. Particle Physics Proton-proton collision in the LHC which produces a Higgs boson | CERN Perhaps the most exciting and useful application of quantum computing is studying new physics. Models of particle physics are remarkably complex, requiring a large number of resources and lengthy computing tim...
problems that were regarded as most relevant, and, for the formalism,quantum mechanicsbecame a dominating foundation. Basic physics, at that time was far away from the irregular structure of living cells, which are driven far from thermal equilibrium, where linear generalisations could not do much...
Nature Reviews Physics volume 2, pages 382–390 (2020)Cite this article 3768 Accesses 24 Altmetric Metrics details Abstract With the rapid development of quantum technologies, a pressing need has emerged for a wide array of tools for the certification and characterization of quantum devices. Such ...
In physics, for any two state vectors, the inner product 〈𝜓|𝜙〉 is typically interpreted as the probability amplitude for the state |𝜙〉 to collapse into the state |𝜓〉 [1]. Therefore, on the grounds of quantum physics, 𝑚𝑖(|𝑥〉) represents the result of a ...
This means that classical physics, II, can never be the limit ℏ→0ℏ→0 of “pure” quantum theory, I. The quantum description of a system of N entities (for 𝑁>1N>1) cannot be embedded in real spacetime [16]—actually, the very formulation of quantum mechanics precludes its ...
Quantum computing is built on the principles of quantum mechanics, which describe how subatomic particles behave differently from macrolevel physics. But because quantum mechanics provides the foundational laws for our entire universe, on a subatomic level, every system is a quantum system. ...

Quantum key distribution (QKD) [1–9] allows legitimate parties, Alice and Bob, to share secure keys through an insecure quantum channel. The fundamental theorems of the quantum physics guarantee that non-orthogonal quantum states transmit through a quantum channel cannot be replicated accurately. Fu...
internal (spin) degree of freedom of the ion, or two-qubit operations by coupling to both the internal and external (collective motional) degrees of freedom. We realize EASE gates by coupling the internal and external degrees of freedom of many ions simultaneously with segmented AM laser pulses...
