Bias-preserving and error-detectable entangling operations in a superconducting dual-rail system
Nitish Mehta, James D. Teoh, Taewan Noh +69
For useful quantum computation, error-corrected machines are required that can dramatically reduce the inevitable errors experienced by physical qubits. While significant progress…
Erasure detection of a dual-rail qubit encoded in a double-post superconducting cavity
Akshay Koottandavida, Ioannis Tsioutsios, Aikaterini Kargioti +8
Qubits with predominantly erasure errors present distinctive advantages for quantum error correction(QEC) and fault tolerant quantum computing. Logical qubits based on dual-rail en…
Demonstrating a superconducting dual-rail cavity qubit with erasure-detected logical measurements
Kevin S. Chou, Tali Shemma, Heather McCarrick +31
A critical challenge in developing scalable error-corrected quantum systems is the accumulation of errors while performing operations and measurements. One promising approach is to…
Error-detectable bosonic entangling gates with a noisy ancilla
Takahiro Tsunoda, James D. Teoh, William D. Kalfus +6
Bosonic quantum error correction has proven to be a successful approach for extending the coherence of quantum memories, but to execute deep quantum circuits, high-fidelity gates b…
A high on-off ratio beamsplitter interaction for gates on bosonically encoded qubits
Benjamin J. Chapman, Stijn J. de Graaf, Sophia H. Xue +12
Encoding a qubit in a high quality superconducting microwave cavity offers the opportunity to perform the first layer of error correction in a single device, but presents a challen…
Precision measurement of the microwave dielectric loss of sapphire in the quantum regime with parts-per-billion sensitivity
Alexander P. Read, Benjamin J. Chapman, Chan U Lei +5
Dielectric loss is known to limit state-of-the-art superconducting qubit lifetimes. Recent experiments imply upper bounds on bulk dielectric loss tangents on the order of par…
Drive-induced nonlinearities of cavity modes coupled to a transmon ancilla
Yaxing Zhang, Jacob C. Curtis, Christopher S. Wang +2
High-Q microwave cavity modes coupled to transmon ancillas provide a hardware-efficient platform for quantum computing. Due to their coupling, the cavity modes inherit finite nonli…
Single-shot number-resolved detection of microwave photons with error mitigation
Jacob C. Curtis, Connor T. Hann, Salvatore S. Elder +4
Single-photon detectors are ubiquitous and integral components of photonic quantum cryptography, communication, and computation. Many applications, however, require not only detect…
