Verification of Linear Optical Quantum Computing using Quantum Process Calculus [PDF]
Electronic Proceedings in Theoretical Computer Science, 2014 We explain the use of quantum process calculus to describe and analyse linear optical quantum computing (LOQC). The main idea is to define two processes, one modelling a linear optical system and the other expressing a specification, and prove that they ...

Thermodynamic Implementations of Quantum Processes [PDF]
Communications in Mathematical Physics, 2021 AbstractRecent understanding of the thermodynamics of small-scale systems have enabled the characterization of the thermodynamic requirements of implementing quantum processes for fixed input states. Here, we extend these results to construct optimal universal implementations of a given process, that is, implementations that are accurate for any ...

Real-Time Experimental Measurement of Swept Source VCSEL Properties Relevant to OCT Imaging
IEEE Photonics Journal, 2017 A real-time study of the dynamic properties of a frequency swept vertical cavity surface emitting laser (VCSEL) is presented. Such tunable laser sources have previously been shown to provide long coherence lengths and improved performance in metrology ...

Dephasing effect promotes the appearance of quantized Hall plateaus
New Journal of Physics, 2023 The quantum Hall effect (QHE) is a topologically protected phenomenon which has been observed in various systems. In experiments, the size of Hall bar device to realize the QHE is generally much larger than the phase coherence length, in which the ...

Quantum stochastic processes III [PDF]
Communications in Mathematical Physics, 1970 We investigate properties of a class of quantum stochastic processes subject to a condition of irreducibility. These processes must be recurrent or transient and an equilibrium state can only exist in the former case. Every finite dimensional process is recurrent and it is possible to establish convergence in time to a unique equilibrium state.

Quantum Computation as a Dynamical Process [PDF]
, 1999 In this paper, we discuss the dynamical issues of quantum computation. We demonstrate that fast wave function oscillations can affect the performance of Shor's quantum algorithm by destroying required quantum interference.

Fourier’s Quantum Information Processing [PDF]
SN Computer Science, 2021 We demonstrate that quantum information processing (QIP) completely rests on quantum Fourier transform (QFT), and 190 years after his death, the work of Jean-Baptiste Joseph Fourier is more present than ever in Physics, constituting the heart of QIP, and showing the spectral nature of quantum entanglement, quantum teleportation, and quantum secret ...

Bisimulation for quantum processes [PDF]
ACM SIGPLAN Notices, 2011 Quantum cryptographic systems have been commercially available, with a striking advantage over classical systems that their security and ability to detect the presence of eavesdropping are provable based on the principles of quantum mechanics. On the other hand, quantum protocol designers may commit much more faults than classical protocol designers ...
