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…
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…
Encoding a magic state with beyond break-even fidelity
Riddhi S. Gupta, Neereja Sundaresan, Thomas Alexander +10
To run large-scale algorithms on a quantum computer, error-correcting codes must be able to perform a fundamental set of operations, called logic gates, while isolating the encoded…
High-fidelity superconducting quantum processors via laser-annealing of transmon qubits
Eric J. Zhang, Srikanth Srinivasan, Neereja Sundaresan +19
Scaling the number of qubits while maintaining high-fidelity quantum gates remains a key challenge for quantum computing. Presently, superconducting quantum processors with >50-qub…
Reducing unitary and spectator errors in cross resonance with optimized rotary echoes
Neereja Sundaresan, Isaac Lauer, Emily Pritchett +3
We present an improvement to the cross resonance gate realized with the addition of resonant, target rotary pulses. These pulses, applied directly to the target qubit, are simultan…
