Robust optical readout and characterization of nuclear spin transitions in nitrogen-vacancy ensembles in diamond
A. Jarmola, I. Fescenko, V. M. Acosta +5
Nuclear spin ensembles in diamond are promising candidates for quantum sensing applications, including rotation sensing. Here we perform a characterization of the optically detecte…
Reframing SU(1,1) interferometry
Carlton M. Caves
SU(1,1) interferometry, proposed in a classic 1986 paper by Yurke, McCall, and Klauder [Phys. Rev. A 33, 4033 (1986)], involves squeezing, displacing, and then unsqueezing two boso…
Robust Mølmer-Sørensen gate for neutral atoms using rapid adiabatic Rydberg dressing
Anupam Mitra, Michael J. Martin, Grant W. Biedermann +3
The Rydberg blockade mechanism is now routinely considered for entangling qubits encoded in clock states of neutral atoms. Challenges towards implementing entangling gates with hig…
Small, Highly Accurate Quantum Processor for Intermediate-Depth Quantum Simulations
Nathan K. Lysne, Kevin W. Kuper, Pablo M. Poggi +2
Analog quantum simulation is widely considered a step on the path to fault tolerant quantum computation. If based on current noisy hardware, the accuracy of an analog simulator wil…
Improved Boltzmann machines with error corrected quantum annealing
Richard Y. Li, Tameem Albash, Daniel A. Lidar
Boltzmann machines are the basis of several deep learning methods that have been successfully applied to both supervised and unsupervised machine learning tasks. These models assum…
Beating the Standard Quantum Limit for Binary Constellations in the Presence of Phase Noise
L. Kunz, M. T. DiMario, F. E. Becerra +1
Unconventional receivers enable reduction of error rates in optical communication systems below the standard quantum limit (SQL) by implementing discrimination strategies for const…
Quantum-Computing Architecture based on Large-Scale Multi-Dimensional Continuous-Variable Cluster States in a Scalable Photonic Platform
Bo-Han Wu, Rafael N. Alexander, Shuai Liu +1
Quantum computing is a disruptive paradigm widely believed to be capable of solving classically intractable problems. However, the route toward full-scale quantum computers is obst…
Validating a Two Qubit Non-Stoquastic Hamiltonian in Quantum Annealing
Tameem Albash
We propose a two qubit experiment for validating tunable antiferromagnetic interactions in quantum annealing. Such interactions allow the time-dependent Hamiltonian to be non-…
In situ characterization of linear-optical networks in randomized boson sampling
Saleh Rahimi-Keshari, Sima Baghbanzadeh, Carlton M. Caves
We introduce a method for efficient, in situ characterization of linear-optical networks (LONs) in randomized boson-sampling (RBS) experiments. We formulate RBS as a distributed ta…
Measurement reduction in variational quantum algorithms
Andrew Zhao, Andrew Tranter, William M. Kirby +3
Variational quantum algorithms are promising applications of noisy intermediate-scale quantum (NISQ) computers. These algorithms consist of a number of separate prepare-and-measure…
Optimized communication strategies with binary coherent states over phase noise channels
M. T. DiMario, L. Kunz, K Banaszek +1
The achievable rate of information transfer in optical communications is determined by the physical properties of the communication channel, such as the intrinsic channel noise. Bo…
Computational universality of symmetry-protected topologically ordered cluster phases on 2D Archimedean lattices
Austin K. Daniel, Rafael N. Alexander, Akimasa Miyake
What kinds of symmetry-protected topologically ordered (SPTO) ground states can be used for universal measurement-based quantum computation in a similar fashion to the 2D cluster s…
Simulating nonlinear dynamics of collective spins via quantum measurement and feedback
Manuel H. Muñoz-Arias, Pablo M. Poggi, Poul S. Jessen +1
We study a method to simulate quantum many-body dynamics of spin ensembles using measurement-based feedback. By performing a weak collective measurement on a large ensemble of two-…
Stereodynamical control of a quantum scattering resonance in cold molecular collisions
Pablo G. Jambrina, James F. E. Croft, Hua Guo +3
Cold collisions of light molecules are often dominated by a single partial wave resonance. For the rotational quenching of HD(v=1,j=2) by collisions with ground state para-H2, the…
