Fast GHZ encoding with fidelity
Laura Shou, T. C. Mooney, Twesh Upadhyaya +1
We prove that -fidelity -qubit Greenberger--Horne--Zeilinger (GHZ) encoding can be performed in time using all-to-all 2-local Hamiltonians with bounded 2…
Thermal Throttling of Quantum State Transfer
Twesh Upadhyaya, T. C. Mooney, Yifan Hong +1
Quantum state transfer on qubit lattices is a crucial step in a panoply of quantum information processing tasks. Understanding its fundamental limits in the presence of practical i…
Robustness-Runtime Tradeoff for Quantum State Transfer
Twesh Upadhyaya, Yifan Hong, T. C. Mooney +1
Quantum state transfer is the primitive of transporting an unknown state on one site of a lattice to another. Using power-law interactions, recent state transfer protocols achieve…
High-Performance Exact Synthesis of Two-Qubit Quantum Circuits
Andrew N. Glaudell, Michael Jarret, Swan Klein +3
Exact synthesis provides unconditional optimality and canonical structure, but is often limited to small, carefully scoped regimes. We present an exact synthesis framework for two-…
The Complexity of Thermalization in Finite Quantum Systems
Dhruv Devulapalli, T. C. Mooney, James D. Watson
Thermalization is the process through which a physical system evolves toward a state of thermal equilibrium. Determining whether or not a physical system will thermalize from an in…
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…
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…
Projective toric designs, quantum state designs, and mutually unbiased bases
Joseph T. Iosue, T. C. Mooney, Adam Ehrenberg +1
Toric -designs, or equivalently -designs on the diagonal subgroup of the unitary group, are sets of points on the torus over which sums reproduce integrals of degree mono…
