Nonlocal Games as Cross-Platform Quantum Benchmarks: Exceeding unconditional classical bounds on trapped-ion processors

Anton T. Than, Jim Furches, Debopriyo Biswas +15

Nonlocal games provide application-level benchmarks for quantum hardware whose classical performance bounds are information-theoretic, holding against all classical strategies rega…

In-situ mid-circuit qubit measurement and reset in a single-species trapped-ion quantum computing system

Yichao Yu, Keqin Yan, Debopriyo Biswas +5

We implement in-situ mid-circuit measurement and reset (MCMR) operations on a trapped-ion quantum computing system by using metastable qubit states in ions. W…

Entanglement fidelity limits of photonically-networked atomic qubits from recoil and timing

Yichao Yu, Sagnik Saha, Mikhail Shalaev +5

The remote entanglement of two atomic quantum memories through photonic interactions is accompanied by atomic momentum recoil. When the interactions occur at different times, such…

Non-invasive mid-circuit measurement and reset on atomic qubits

Zuo-Yao Chen, Isabella Goetting, George Toh +8

Mid-circuit measurement and reset of subsets of qubits is a crucial ingredient of quantum error correction and many quantum information applications. Measurement of atomic qubits i…
