Discovering hydrodynamic equations of many-body quantum systems
Yaroslav Kharkov, Oles Shtanko, Alireza Seif +4
Simulating and predicting dynamics of quantum many-body systems is extremely challenging, even for state-of-the-art computational methods, due to the spread of entanglement across…
Spin-Wave Quantum Computing with Atoms in a Single-Mode Cavity
Kevin C. Cox, Przemyslaw Bienias, David H. Meyer +3
We present a method for network-capable quantum computing that relies on holographic spin-wave excitations stored collectively in ensembles of qubits. We construct an orthogonal ba…
Linear and continuous variable spin-wave processing using a cavity-coupled atomic ensemble
Kevin C. Cox, Przemyslaw Bienias, David H. Meyer +3
Spin-wave excitations in ensembles of atoms are gaining attention as a quantum information resource. However, current techniques with atomic spin waves do not achieve universal qua…
Behavior of Analog Quantum Algorithms
Lucas T. Brady, Lucas Kocia, Przemyslaw Bienias +3
Analog quantum algorithms are formulated in terms of Hamiltonians rather than unitary gates and include quantum adiabatic computing, quantum annealing, and the quantum approximate…
Circuit Quantum Electrodynamics in Hyperbolic Space: From Photon Bound States to Frustrated Spin Models
Przemyslaw Bienias, Igor Boettcher, Ron Belyansky +2
Circuit quantum electrodynamics is one of the most promising platforms for efficient quantum simulation and computation. In recent groundbreaking experiments, the immense flexibili…
Protocols for estimating multiple functions with quantum sensor networks: geometry and performance
Jacob Bringewatt, Igor Boettcher, Pradeep Niroula +2
We consider the problem of estimating multiple analytic functions of a set of local parameters via qubit sensors in a quantum sensor network. To address this problem, we highlight…
Meta Hamiltonian Learning
Przemyslaw Bienias, Alireza Seif, Mohammad Hafezi
Efficient characterization of quantum devices is a significant challenge critical for the development of large scale quantum computers. We consider an experimentally motivated situ…
Singularities in nearly-uniform 1D condensates due to quantum diffusion
C. L. Baldwin, P. Bienias, A. V. Gorshkov +2
Dissipative systems can often exhibit wavelength-dependent loss rates. One prominent example is Rydberg polaritons formed by electromagnetically-induced transparency, which have lo…
Topological bands in the continuum using Rydberg states
Sebastian Weber, Przemyslaw Bienias, Hans Peter Büchler
The quest to realize topological band structures in artificial matter is strongly focused on lattice systems, and only quantum Hall physics is known to appear naturally also in the…
