We investigate the quantum-memory-assisted entropic uncertainty relation between coupled qubits which are initially in entangled mixed states in squeezed vacuum reservoir. We find that the uncertainty of quantum system is dependent on the squeezing effect of optical field. In the squeezed vacuum reservoi...
We study the implications of the generalized uncertainty principle (GUP) with a minimal measurable length on some quantum mechanical interferometry phenomena, such as the Aharonov–Bohm, Aharonov–Casher, COW and Sagnac effects. By resorting to a modified Schrödinger equation, we evaluate the lowest...
The quantum Hall effect (QHE) discovery has revolutionized the ohm metrology: the representation of the unit of resistance is now universal and the ohm can be maintained in each national metrology institute with a relative uncertainty of one part in 109. This breakthrough also results from the ...
With the improvement of computing power and the emergence of quantum algorithms [2,3], the SMC cryptographic protocol based on classical NP problems is repeatedly broken. As an indivisible smallest unit, quantum has its unique properties. The principle of quantum uncertainty makes it impossible for...
Quantum cryptography applies the basic principles of quantum mechanics, such as the uncertainty principle, quantum no-cloning theorem, and quantum entanglement characteristics, to ensure the security of quantum cryptography [9]. Gottesman and Chung pioneered a quantum digital signature scheme based on ...
uncertainty. They would have to break the laws of quantum physics to hack such keys. Imagine that level of security with regards to sensitive medical information: electronic health records, genetic and genomic data, or any other private information that the health system generates about our bodies...

A quantum mechanical effect in which particles have a finite probability of crossing an energy barrier, such as the energy needed to break a bond with another particle, even though the ...

We have also considered impact of the environment with ε=4 on this process. Thus, it can be concluded from data in Table 1 that the environmental effect is insignificant (~1 kcal∙mol−1). It means that considered model of the transformation could adequately reflect the processes in real...
holes in space–time, and while the matter fields can be described by quantum field theory, we only know how to treat space–time classically. Likewise in cosmology, vacuum fluctuations are a quantum effect that we believe seeds galaxy formation, while the expanding space–time they live on ...
