Continuous-variable quantum tomography of high-amplitude states
Ekaterina Fedotova, Nikolai Kuznetsov, Egor Tiunov +2
Quantum state tomography is an essential component of modern quantum technology. In application to continuous-variable harmonic-oscilator systems, such as the electromagnetic field…
Reconstructing complex states of a 20-qubit quantum simulator
Murali K. Kurmapu, V. V. Tiunova, E. S. Tiunov +6
A prerequisite to the successful development of quantum computers and simulators is precise understanding of physical processes occurring therein, which can be achieved by measurin…
Fractal states of the Schwinger model
E. V. Petrova, E. S. Tiunov, M. C. Bañuls +1
The lattice Schwinger model (SM), the discrete version of QED in 1+1 dimensions, is a well-studied test bench for lattice gauge theories. Here we study the fractal properties of th…
Polynomial unconstrained binary optimisation inspired by optical simulation
Dmitry A. Chermoshentsev, Aleksei O. Malyshev, Mert Esencan +5
We propose an algorithm inspired by optical coherent Ising machines to solve the problem of polynomial unconstrained binary optimization (PUBO). We benchmark the proposed algorithm…
Quantum-inspired annealers as Boltzmann generators for machine learning and statistical physics
Alexander E. Ulanov, Egor S. Tiunov, A. I. Lvovsky
Quantum simulators and processors are rapidly improving nowadays, but they are still not able to solve complex and multidimensional tasks of practical value. However, certain numer…
Experimental quantum homodyne tomography via machine learning
E. S. Tiunov, V. V. Tiunova, A. E. Ulanov +2
Complete characterization of states and processes that occur within quantum devices is crucial for understanding and testing their potential to outperform classical technologies fo…
Annealing by simulating the coherent Ising machine
Egor S. Tiunov, Alexander E. Ulanov, A. I. Lvovsky
The coherent Ising machine (CIM) enables efficient sampling of low-lying energy states of the Ising Hamiltonian with all-to-all connectivity by encoding the spins in the amplitudes…
Entanglement and teleportation between polarization and wave-like encodings of an optical qubit
Demid V. Sychev, Alexander E. Ulanov, Anastasia A. Pushkina +3
Light is an irreplaceable means of communication among various quantum information processing and storage devices. Due to their different physical nature, some of these devices cou…
