Programmable Quantum Annealers as Noisy Gibbs Samplers
Marc Vuffray, Carleton Coffrin, Yaroslav A. Kharkov +1
Drawing independent samples from high-dimensional probability distributions represents the major computational bottleneck for modern algorithms, including powerful machine learning…
Quantum teleportation and entanglement swapping with long baseline in outer space
Shih-Yuin Lin, B. L. Hu
Quantum information experiments applying quantum optics in outer space with a very long baseline may have advantages over the current earth-bound experiments or the earth-to-satell…
Energy storage and coherence in closed and open quantum batteries
Francesco Caravelli, Bin Yan, Luis Pedro Garcia-Pintos +1
We study the role of coherence in closed and open quantum batteries. We obtain upper bounds to the work performed or energy exchanged by both closed and open quantum batteries in t…
Fast logic with slow qubits: microwave-activated controlled-Z gate on low-frequency fluxoniums
Quentin Ficheux, Long B. Nguyen, Aaron Somoroff +4
We demonstrate a controlled-Z gate between capacitively coupled fluxonium qubits with transition frequencies and . The gate is activated by…
Optimal Measurement of Field Properties with Quantum Sensor Networks
Timothy Qian, Jacob Bringewatt, Igor Boettcher +2
We consider a quantum sensor network of qubit sensors coupled to a field analytically parameterized by the vector of parameters . The qubit sensors are fi…
Proposal for entangling gates on fluxonium qubits via a two-photon transition
Konstantin N. Nesterov, Quentin Ficheux, Vladimir E. Manucharyan +1
We propose a family of microwave-activated entangling gates on two capacitively coupled fluxonium qubits. A microwave pulse applied to either qubit at a frequency near the half-fre…
Reversible Fluxon Logic with optimized CNOT gate components
Kevin D. Osborn, Waltraut Wustmann
Reversible logic gates were previously implemented in superconducting circuits as adiabatic-reversible gates, which are powered with a sufficiently slow clock. In contrast, we are…
Single-shot readout of a solid-state spin in a decoherence-free subspace
D. Farfurnik, R. M. Pettit, Z. Luo +1
The efficient single photon emission capabilities of quantum dot molecules position them as promising platforms for quantum information processing. Furthermore, quantum dot molecul…
Circulation by microwave-induced vortex transport for signal isolation
Brittany Richman, Jacob M. Taylor
Magnetic fields break time-reversal symmetry, which is leveraged in many settings to enable the nonreciprocal behavior of light. This is the core physics of circulators and other e…
Optimal State Transfer and Entanglement Generation in Power-law Interacting Systems
Minh C. Tran, Abhinav Deshpande, Andrew Y. Guo +2
We present an optimal protocol for encoding an unknown qubit state into a multiqubit Greenberger-Horne-Zeilinger-like state and, consequently, transferring quantum information in l…
Tunable three-body loss in a nonlinear Rydberg medium
Dalia P. Ornelas Huerta, Przemyslaw Bienias, Alexander N. Craddock +7
Long-range Rydberg interactions, in combination with electromagnetically induced transparency (EIT), give rise to strongly interacting photons where the strength, sign, and form of…
Light-matter interactions in synthetic magnetic fields: Landau-photon polaritons
Daniele De Bernardis, Ze-Pei Cian, Iacopo Carusotto +2
We study light-matter interactions in two dimensional photonic systems in the presence of a spatially homogeneous synthetic magnetic field for light. Specifically, we consider one…
Symmetry breaking and error correction in open quantum systems
Simon Lieu, Ron Belyansky, Jeremy T. Young +3
Symmetry-breaking transitions are a well-understood phenomenon of closed quantum systems in quantum optics, condensed matter, and high energy physics. However, symmetry breaking in…
Entanglement entropy scaling transition under competing monitoring protocols
Mathias Van Regemortel, Ze-Pei Cian, Alireza Seif +2
Dissipation generally leads to the decoherence of a quantum state. In contrast, numerous recent proposals have illustrated that dissipation can also be tailored to stabilize many-b…
Many-body Signatures of Collective Decay in Atomic Chains
Stuart J. Masson, Igor Ferrier-Barbut, Luis A. Orozco +2
Fully inverted atoms placed at exactly the same location synchronize as they deexcite, and light is emitted in a burst (known as "Dicke's superradiance"). We investigate the role o…

Donovan Buterakos, Sankar Das Sarma, Edwin Barnes
The ability to perform gates in multiqubit systems that are robust to noise is of crucial importance for the advancement of quantum information technologies. However, finding contr…

Continuing our work on the nature and existence of fluctuation-dissipation relations (FDR) in linear and nonlinear open quantum systems [1-3], here we consider such relations when…

Abhinav Deshpande, Alexey V. Gorshkov, Bill Fefferman
The field of quantum Hamiltonian complexity lies at the intersection of quantum many-body physics and computational complexity theory, with deep implications to both fields. The ma…
Optical quantum memory for noble-gas spins based on spin-exchange collisions
