Dual-Resonator Kinetic-Inductance Detector for Distinction between Signal and 1/f Frequency Noise
N. Foroozani, B. Sarabi, S. H. Moseley +4
Astronomical Kinetic Inductance Detectors (KIDs), similar to quantum information devices, experience performance limiting noise from materials. In particular, 1/f (frequency) noise…
Probing hundreds of individual quantum defects in polycrystalline and amorphous alumina
Chih-Chiao Hung, Liuqi Yu, Neda Foroozani +3
Quantum two-level systems (TLSs) are present in the materials of qubits and are considered defects because they limit qubit coherence. For superconducting qubits, the quintessentia…
Development of transmon qubits solely from optical lithography on 300mm wafers
N. Foroozani, C. Hobbs, C. C. Hung +21
Qubit information processors are increasing in footprint but currently rely on e-beam lithography for patterning the required Josephson junctions (JJs). Advanced optical lithograph…
Homodyne monitoring of post-selected decay
D. Tan, N. Foroozani, M. Naghiloo +3
We use homodyne detection to monitor the radiative decay of a superconducting qubit. According to the classical theory of conditional probabilities, the excited state population di…
Mapping quantum state dynamics in spontaneous emission
M. Naghiloo, N. Foroozani, D. Tan +2
The evolution of a quantum state undergoing radiative decay depends on how the emission is detected. We employ phase-sensitive amplification to perform homodyne detection of the sp…
Correlations of the time dependent signal and the state of a continuously monitored quantum system
N. Foroozani, M. Naghiloo, D. Tan +2
In quantum physics, measurements give random results and yield a corresponding random back action on the state of the system subject to measurement. If a quantum system is probed c…
Suppression of dense Kondo state in CeB6 under pressure
N. Foroozani, J. Lim, G. Fabbris +3
To investigate whether the dense Kondo compound CeB6 might evolve into a topological insulator under sufficient pressure, four-point electrical resistivity measurements have been c…
Upper critical field of KFe2As2 under pressure: A test for the change in the superconducting gap structure
Valentin Taufour, Neda Foroozani, Jinhyuk Lim +10
We report measurements of electrical resistivity under pressure to 5.8 GPa, magnetization to 6.7 GPa,and ac susceptibility to 7.1 GPa in KFe2As2. The previously reported change of…
