Noise structuring in fixed-depth Trotter simulation: stationary channels and observable-level depolarization
G. L. Stavisskii, W. V. Pogosov, L. E. Fedichkin +1
We analyze fixed-depth Trotter simulation as a method for structuring hardware noise in digital many-body dynamics. The number of layers is chosen using the largest endpoint time a…
Dynamics of quantum measurement via electron transport in quantum dot systems: many-particle wavefunction approach
George Stavisskii, Leonid Fedichkin
Measurement of a charge qubit via point contacts with complex internal structures is considered. In this context, a fully formalized derivation of the many-body wave function metho…
High-dimensional graphs convolution for quantum walks photonic applications
Roman Abramov, Leonid Fedichkin, Dmitry Tsarev +1
Quantum random walks represent a powerful tool for the implementation of various quantum algorithms. We consider a convolution problem for the graphs which provide quantum and clas…
Quantum register based on double quantum dots in semiconductor nanowires
Vladimir Vyurkov, Leonid Fedichkin, Igor Semenikhin +3
An implementation of a universal solid-state quantum register based on electron space states in field-defined double quantum dots (a DQD possesses one electron in two adjacent tunn…
An exponentially-growing family of universal quantum circuits
Mo Kordzanganeh, Pavel Sekatski, Leonid Fedichkin +1
Quantum machine learning has become an area of growing interest but has certain theoretical and hardware-specific limitations. Notably, the problem of vanishing gradients, or barre…
Quantum walk processes in quantum devices
Anandu Kalleri Madhu, Alexey A. Melnikov, Leonid E. Fedichkin +2
Simulation and programming of current quantum computers as Noisy Intermediate-Scale Quantum (NISQ) devices represent a hot topic at the border of current physical and information s…
