Quantum dial
Aashish Sah, Suman Kundu, Priyank Singh +3
Accurate control of quantum degrees of freedom is promising for sensing, communication, and computing, but building a useful quantum computer faces a central isolation-and-control…
Computed tomography of propagating microwave photons
Qi-Ming Chen, Aarne Keränen, Aashish Sah +1
Propagating photons serve as essential links for distributing quantum information and entanglement across distant nodes. Knowledge of their Wigner functions not only enables their…
Decay-protected superconducting qubit with fast control enabled by integrated on-chip filters
Aashish Sah, Suman Kundu, Heikki Suominen +2
Achieving fast gates and long coherence times for superconducting qubits presents challenges, typically requiring either a stronger coupling of the drive line or an excessively str…
Many-excitation removal of a transmon qubit using a single-junction quantum-circuit refrigerator and a two-tone microwave drive
Wallace Teixeira, Timm Mörstedt, Arto Viitanen +7
Achieving fast and precise initialization of qubits is a critical requirement for the successful operation of quantum computers. The combination of engineered environments with all…
