Toward a Scalable Linear-Cavity Enhanced Warm-Vapor Photonic Quantum Memory
Bharath Srivathsan, Rafal Gartman, Robert J. A. Francis-Jones +2
The coherent storage, buffering and retrieval of photons in a quantum memory enables the scalable creation of photonic entangled states via linear optics and repeat-until-success,…
Fast, low-loss all-optical phase modulation in warm rubidium vapour
William Davis, Paul Burdekin, Tabijah Wasawo +4
Low-loss high-speed switches are an integral component of future photonic quantum technologies, with applications in state generation, multiplexing, and the implementation of quant…
Determining the ability for universal quantum computing: Testing controllability via dimensional expressivity
Fernando Gago-Encinas, Tobias Hartung, Daniel M. Reich +2
Operator controllability refers to the ability to implement an arbitrary unitary in SU(N) and is a prerequisite for universal quantum computing. Controllability tests can be used i…
Towards Finding an Optimal Flight Gate Assignment on a Digital Quantum Computer
Yahui Chai, Lena Funcke, Tobias Hartung +4
We investigate the performance of the variational quantum eigensolver (VQE) for the optimal flight gate assignment problem. This problem is a combinatorial optimization problem tha…
Critical behavior of Ising model by preparing thermal state on quantum computer
Xiaoyang Wang, Xu Feng, Tobias Hartung +2
We simulate the critical behavior of the Ising model utilizing a thermal state prepared using quantum computing techniques. The preparation of the thermal state is based on the var…
Classical Splitting of Parametrized Quantum Circuits
Cenk Tüysüz, Giuseppe Clemente, Arianna Crippa +3
Barren plateaus appear to be a major obstacle to using variational quantum algorithms to simulate large-scale quantum systems or replace traditional machine learning algorithms. Th…
