A promising quantum computing architecture comprises modules of superconducting quantum processors linked via optical channels using quantum transducers. As quantum transducer hard…
Randomized benchmarking of a high-fidelity remote CNOT gate over a meter-scale microwave interconnect
Kentaro Heya, Timothy Phung, Moein Malekakhlagh +8
High-fidelity, meter-scale microwave interconnects between superconducting quantum processor modules are a key technology for extending system size beyond constraints imposed by de…
Teleportation and Entanglement Swapping of Continuous Quantum Variables of Microwave Radiation
Baleegh Abdo, William Shanks, Oblesh Jinka +2
Quantum communication is needed to build powerful quantum computers and establish reliable quantum networks. At its basis lies the ability to generate and distribute entanglement t…
Mechanically-intermixed indium superconducting connections for microwave quantum interconnects
Yves Martin, Neereja Sundaresan, Jae-woong Nah +5
Superconducting coaxial cables represent critical communication channels for interconnecting superconducting quantum processors. Here, we report mechanically-intermixed indium join…
Enhanced Quantum State Transfer and Bell State Generation over Long-Range Multimode Interconnects via Superadiabatic Transitionless Driving
Moein Malekakhlagh, Timothy Phung, Daniel Puzzuoli +3
Achieving high-fidelity direct two-qubit gates over meter-scale long quantum interconnects is challenging in part due to the multimode nature of such systems. One alternative schem…
