Large Fluctuations in Open Quantum Systems
V. Yu. Mylnikov, S. O. Potashin, A. Kamenev
We study statistics of atypical measurement outcomes in the steady states of driven open quantum systems. In equilibrium, the probability distribution over the phase space, as enco…
Spectroscopy of Quantum Phase Slips: Visualizing Complex Real-Time Instantons
Foster Thompson, Daniel K. J. Boneß, Mark Dykman +1
Parametrically driven oscillators can emerge as a basis for the next generation of qubits. Classically, these systems exhibit two stable oscillatory states with opposite phases. Up…
Qubit decoherence in dissipative two-photon resonator: real-time instantons and Wigner function
V. Yu. Mylnikov, S. O. Potashin, Alex Kamenev
We study the quantum dynamics of a single bosonic cavity subject to two-photon driving and two-photon dissipation in the presence of finite detuning. Exploiting a hidden time-rever…
Quantum sequel of neural network training
Hao Zhang, Alex Kamenev
Training of neural networks (NNs) has emerged as a major consumer of both computational and energy resources. Quantum computers were coined as a root to facilitate training, but no…
Schmid-Higgs Mode in the Presence of Pair-Breaking Interactions
Maxim Dzero, Alex Kamenev
Collective modes in superconductors provided the first realization of the Higgs mechanism. The transverse Goldstone mode acquires a gap (i.e. a mass) when it hybridizes with the el…
Computational complexity of three-dimensional Ising spin glass: Lessons from D-Wave annealer
Hao Zhang, Alex Kamenev
Finding an exact ground state of a three-dimensional (3D) Ising spin glass is proven to be an NP-hard problem (i.e., at least as hard as any problem in the nondeterministic polynom…
