Experimental Demonstration of Logical Magic State Distillation
Pedro Sales Rodriguez, John M. Robinson, Paul Niklas Jepsen +70
Realizing universal fault-tolerant quantum computation is a key goal in quantum information science. By encoding quantum information into logical qubits utilizing quantum error cor…
Enhancing Dynamic Range of Sub-Quantum-Limit Measurements via Quantum Deamplification
Qi Liu, Ming Xue, Matthew Radzihovsky +4
Balancing high sensitivity with a broad dynamic range is a fundamental challenge in measurement science, as improving one often compromises the other. While traditional quantum met…
Cavity-enabled real-time observation of individual atomic collisions
Matthew L. Peters, Guoqing Wang, David C. Spierings +4
Using the strong dispersive coupling to a high-cooperativity cavity, we demonstrate fast and non-destructive number-resolved detection of atoms in optical tweezers. We observe indi…
Error-Detected Quantum Operations with Neutral Atoms Mediated by an Optical Cavity
Brandon Grinkemeyer, Elmer Guardado-Sanchez, Ivana Dimitrova +5
Neutral atom quantum processors are a promising platform for large-scale quantum computing. Integrating them with an optical cavity enables fast nondestructive qubit readout and ac…
Site-selective cavity readout and classical error correction of a 5-bit atomic register
Beili Hu, Josiah Sinclair, Edita Bytyqi +5
Optical cavities can provide fast and non-destructive readout of individual atomic qubits; however, scaling up to many qubits remains a challenge. Using locally addressed excited-s…
Fault-tolerant optical interconnects for neutral-atom arrays
Josiah Sinclair, Joshua Ramette, Brandon Grinkemeyer +3
We analyze the use of photonic links to enable large-scale fault-tolerant connectivity of locally error-corrected modules based on neutral atom arrays. Our approach makes use of re…
Quantum coarsening and collective dynamics on a programmable simulator
Tom Manovitz, Sophie H. Li, Sepehr Ebadi +15
Understanding the collective quantum dynamics of nonequilibrium many-body systems is an outstanding challenge in quantum science. In particular, dynamics driven by quantum fluctuat…
