Entanglement bounds on the performance of quantum computing architectures
Zachary Eldredge, Leo Zhou, Aniruddha Bapat +4
There are many possible architectures of qubit connectivity that designers of future quantum computers will need to choose between. However, the process of evaluating a particular…
Nondestructive cooling of an atomic quantum register via state-insensitive Rydberg interactions
Ron Belyansky, Jeremy T. Young, Przemyslaw Bienias +4
We propose a protocol for sympathetically cooling neutral atoms without destroying the quantum information stored in their internal states. This is achieved by designing state-inse…
Heisenberg-Scaling Measurement Protocol for Analytic Functions with Quantum Sensor Networks
Kevin Qian, Zachary Eldredge, Wenchao Ge +4
We generalize past work on quantum sensor networks to show that, for input parameters, entanglement can yield a factor improvement in mean squared error when es…
Unitary Entanglement Construction in Hierarchical Networks
Aniruddha Bapat, Zachary Eldredge, James R. Garrison +3
The construction of large-scale quantum computers will require modular architectures that allow physical resources to be localized in easy-to-manage packages. In this work, we exam…
Locality and digital quantum simulation of power-law interactions
Minh C. Tran, Andrew Y. Guo, Yuan Su +5
The propagation of information in non-relativistic quantum systems obeys a speed limit known as a Lieb-Robinson bound. We derive a new Lieb-Robinson bound for systems with interact…
Scale-Invariant Continuous Entanglement Renormalization of a Chern Insulator
Su-Kuan Chu, Guanyu Zhu, James R. Garrison +5
The multi-scale entanglement renormalization ansatz (MERA) postulates the existence of quantum circuits that renormalize entanglement in real space at different length scales. Cher…
