Deterministic linear-optical computing with symmetry-based qubits
David S. Simon, Christopher R. Schwarze, Anthony D. Manni +2
A particular type of linear optical multiport, the Grover four-port, has previously been shown to couple the spatial symmetry of a photon to its direction of travel. It is shown he…
Entanglement Assisted Non-local Optical Interferometry in a Quantum Network
P. -J. Stas, Y. -C. Wei, M. Sirotin +13
The sensitivity of non-local optical measurements at low light intensities, such as those involved in long baseline telescope arrays, can be improved by using remote entanglement.…
Dynamics of disordered quantum systems with two- and three-dimensional tensor networks
Joseph Tindall, Antonio Mello, Matt Fishman +2
Large scale quantum annealing dynamics of Ising spin glasses were recently implemented on D-Wave's Advantage system on a range of lattices. Following extensive comparison to exi…
Universal Counterdiabatic Driving
Stewart Morawetz, Anatoli Polkovnikov
Local counterdiabatic (CD) driving provides a systematic way of constructing a control protocol to approximately suppress the excitations resulting from changing some parameter(s)…
Universal distributed blind quantum computing with solid-state qubits
Yan-Cheng Wei, Pieter-Jan Stas, Aziza Suleymanzade +16
Blind quantum computing (BQC) is a promising application of distributed quantum systems, where a client can perform computations on a remote server without revealing any details of…
An Improved Bound on Nonlinear Quantum Mechanics using a Cryogenic Radio Frequency Experiment
Oleksandr Melnychuk, Bianca Giaccone, Nicholas Bornman +9
There are strong arguments that quantum mechanics may be nonlinear in its dynamics. A discovery of nonlinearity would hint at a novel understanding of the interplay between gravity…

H. O. Cildiroglu
In this study, a novel experimental setup analogous to joint spin/polarization measurement experiments is proposed by establishing a direct relationship between path (momentum) ent…
Cloning Games, Black Holes and Cryptography
Alexander Poremba, Seyoon Ragavan, Vinod Vaikuntanathan
In this work, we introduce a new toolkit for analyzing cloning games, a notion that captures stronger and more quantitative versions of the celebrated quantum no-cloning theorem. T…
Autonomous Stabilization of Floquet States Using Static Dissipation
Martin Ritter, David M. Long, Qianao Yue +2
Floquet engineering, in which the properties of a quantum system are modified through the application of strong periodic drives, is an indispensable tool in atomic and condensed ma…
Single-photon description of the lossless optical Y coupler
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +1
Using symmetry considerations, we derive a unitary scattering matrix for a three-port optical Y-coupler or Y-branch. The result is shown to be unique up to external phase shifts. U…
