Minimal Energy Cost to Initialize a Quantum Bit with Tolerable Error
Yu-Han Ma, Jin-Fu Chen, C. P. Sun +1
Landauer's principle imposes a fundamental limit on the energy cost to perfectly initialize a classical bit, which is only reached under the ideal operation with infinite-long time…
A simple relation of guessing probability in quantum key distribution
Hong-Yi Su
Given a communication system using quantum key distribution, the receiver can be seen as one who tries to guess the sender's information just as potential eavesdroppers do. The rec…
Error statistics and scalability of quantum error mitigation formulas
Dayue Qin, Yanzhu Chen, Ying Li
Quantum computing promises advantages over classical computing in many problems. Nevertheless, noise in quantum devices prevents most quantum algorithms from achieving the quantum…
Criterion for a state to be distillable via stochastic incoherent operations
C. L. Liu, D. L. Zhou, C. P. Sun
Coherence distillation is a basic information-theoretic task in the resource theory of coherence. In this paper, we present the necessary and sufficient conditions under which a mi…
Error-mitigated deep-circuit quantum simulation of open systems: steady state and relaxation rate problems
Anbang Wang, Jingning Zhang, Ying Li
Deep-circuit quantum computation, like Shor's algorithm, is undermined by error accumulation, and near-future quantum techniques are far from adequate for full-fledged quantum erro…
The Variational Quantum Eigensolver: a review of methods and best practices
Jules Tilly, Hongxiang Chen, Shuxiang Cao +8
The variational quantum eigensolver (or VQE) uses the variational principle to compute the ground state energy of a Hamiltonian, a problem that is central to quantum chemistry and…
