Quantum error correction provides a path to fault-tolerant quantum computation, even in the presence of noisy hardware. However, it comes at the cost of a large overhead; many physical qubits are required to encode a single, error-corrected logical qubit. Fortunately, this overhead may be mitigated by using hardware with structured noise. In particular, erasure errors — that is, detected loss...

Superconducting quantum processors have been established to explore quantum physics [1] and some made accessible to the general public [2]. However, their operation of this large-scale quantum processor prevents the users from full control (e.g. pulse-level control of the processors). Furthermore, their queuing system and charging plan [3] make it difficult to run experiment that requires long...

Superconducting quantum technologies have emerged as a leading platform for quantum computing and quantum sensing over the past three decades. A key enabling component in these systems is the quantum-limited amplifier (QLA), which is essential for high-fidelity qubit readout and has also found important applications in areas such as dark matter detection [1]. State-of-the-art QLAs are...

Multiple leading quantum computing technology platforms are based on microwave-frequency qubits embedded in superconducting electronic circuits. Due to loss and decoherence constraints, these systems require cryogenic environments and electromagnetic shielding to suppress unwanted electromagnetic interactions, blackbody radiation, quasiparticle interactions and spurious modes that can degrade...
