The Kerr-Cat Qubit: Stabilization, Readout, and Gates
Alexander Grimm, Nicholas E. Frattini, Shruti Puri +6
Quantum superpositions of macroscopically distinct classical states, so-called Schrödinger cat states, are a resource for quantum metrology, quantum communication, and quantum comp…
Quantum critical scaling of the conductivity tensor at the metal-insulator transition in NbTiN
D. Hazra, Prosenjit Haldar, M. S. Laad +12
In contrast to the Landau paradigm, a metal-insulator transition (MIT), driven purely by competition between itinerance and localization and unaccompanied by any conventional (e.g,…
Bias-preserving gates with stabilized cat qubits
Shruti Puri, Lucas St-Jean, Jonathan A. Gross +9
The code capacity threshold for error correction using qubits which exhibit asymmetric or biased noise channels is known to be much higher than with qubits without such structured…
A self-aligned nano-fabrication process for vertical NbN-MgO-NbN Josephson junctions
A. Grimm, S. Jebari, D. Hazra +4
We present a new process for fabricating vertical NbN-MgO-NbN Josephson junctions using self-aligned silicon nitride spacers. It allows for a wide range of junction areas from 0.02…
Antibunched photons from inelastic Cooper-pair tunneling
Juha Leppäkangas, Mikael Fogelström, Alexander Grimm +3
We demonstrate theoretically that charge transport across a Josephson junction, voltage-biased through a resistive environment, produces antibunched photons. We develop a continuou…
