Hybrid digital-analog protocols for simulating quantum multi-body interactions
Or Katz, Alexander Schuckert, Tianyi Wang +3
While quantum simulators promise to explore quantum many-body physics beyond classical computation, their capabilities are limited by the available native interactions in the hardw…
Low-depth fermion routing without ancillas
Nathan Constantinides, Jeffery Yu, Dhruv Devulapalli +6
Routing is the task of permuting qubits in such a way that quantum operations can be parallelized maximally, given constraints on the hardware geometry. When simulating fermions in…
Measurement-induced entanglement in noisy 2D random circuits
Zhi-Yuan Wei, Jon Nelson, Joel Rajakumar +4
We study measurement-induced entanglement (MIE) generated by column-by-column sampling of noisy 2D random circuits of size and depth . Focusing primarily on Clifford circuit…
Measuring gravitational lensing time delays with quantum information processing
Zhenning Liu, William DeRocco, Shiming Gu +6
The gravitational fields of astrophysical bodies bend the light around them, creating multiple paths along which light from a distant source can arrive at Earth. Measuring the diff…
Data-insensitive cooling of polar molecules with Rydberg atoms
Jeremy T. Young, Ron Belyansky, Kang-Kuen Ni +1
We propose a method to sympathetically cool polar molecules with Rydberg atoms without destroying the quantum information encoded in the polar molecules. While the interactions bet…
Cavity-mediated cross-cross-resonance gate
Alexey V. Gorshkov, Daniel Cohen, Arbel Haim +8
We propose a cavity-mediated gate between two transmon qubits or other nonlinear superconducting elements. The gate is realized by driving both qubits at a frequency that is near-r…
Time Independence Does Not Limit Information Flow. I. The Free-Particle Case
Dong Yuan, Chao Yin, T. C. Mooney +3
The speed of information propagation in long-range interacting quantum systems is limited by Lieb-Robinson-type bounds, whose tightness can be established by finding specific quant…
Quantum Routing and Entanglement Dynamics Through Bottlenecks
Dhruv Devulapalli, Chao Yin, Andrew Y. Guo +4
To implement arbitrary quantum circuits in architectures with restricted interactions, one may effectively simulate all-to-all connectivity by routing quantum information. We consi…
Quantum simulation of bubble nucleation across a quantum phase transition
De Luo, Federica Maria Surace, Arinjoy De +8
The liquid-vapor transition is a classic example of a discontinuous (first-order) phase transition. Such transitions underlie many phenomena in cosmology, nuclear and particle phys…
Time Independence Does Not Limit Information Flow. II. The Case with Ancillas
T. C. Mooney, Dong Yuan, Adam Ehrenberg +3
While the impact of locality restrictions on quantum dynamics and algorithmic complexity has been well studied in the general case of time-dependent Hamiltonians, the capabilities…
A quantum monomer-dimer model on Penrose tilings
Jeet Shah, Gautam Nambiar, Alexey V. Gorshkov +1
We define a quantum monomer-dimer model in the space of maximal dimer coverings of quasicrystalline Penrose tilings. Since Penrose tilings do not admit perfect dimer coverings, as…
Dynamical complexity of non-Gaussian many-body systems with dissipation
Guillermo González-García, Alexey V. Gorshkov, J. Ignacio Cirac +1
We characterize the dynamical state of many-body bosonic and fermionic many-body models with inter-site Gaussian couplings, on-site non-Gaussian interactions and local dissipation…
