Crosstalk-Robust Quantum Control in Multimode Bosonic Systems
Xinyuan You, Yunwei Lu, Taeyoon Kim +10
High-coherence superconducting cavities offer a hardware-efficient platform for quantum information processing. To achieve universal operations of these bosonic modes, the requisit…
Systematic Improvements in Transmon Qubit Coherence Enabled by Niobium Surface Encapsulation
Mustafa Bal, Akshay A. Murthy, Shaojiang Zhu +37
We present a novel transmon qubit fabrication technique that yields systematic improvements in T relaxation times. We fabricate devices using an encapsulation strategy that inv…
Quantum computing hardware for HEP algorithms and sensing
M. Sohaib Alam, Sergey Belomestnykh, Nicholas Bornman +37
Quantum information science harnesses the principles of quantum mechanics to realize computational algorithms with complexities vastly intractable by current computer platforms. Ty…
Positive- and negative-frequency noise from an ensemble of two-level fluctuators
Xinyuan You, Aashish A. Clerk, Jens Koch
The analysis of charge noise based on the Bloch-Redfield treatment of an ensemble of dissipative two-level fluctuators generally results in a violation of the fluctuation-dissipati…
Experimental realization of an intrinsically error-protected superconducting qubit
Andras Gyenis, Pranav S. Mundada, Agustin Di Paolo +6
Encoding a qubit in logical quantum states with wavefunctions characterized by disjoint support and robust energies can offer simultaneous protection against relaxation and pure de…
Circuit quantization in the presence of time-dependent external flux
Xinyuan You, J. A. Sauls, Jens Koch
Circuit quantization links a physical circuit to its corresponding quantum Hamiltonian. The standard quantization procedure generally assumes any external magnetic flux to be stati…
