Anderson Orthogonality as Measurement Backaction in Coupled Quantum Dots
Will Grant, Sarath Sankar, Elena Cornick +9
Measurement perturbs a quantum system by coupling it to external degrees of freedom, but detector backaction depends on the physical mechanism of measurement itself. In solid-state…
Entropic signatures of the single-impurity Kondo state
Johann Drayne, Silvia Lüscher, Will Grant +8
The paper reports a thermodynamic measurement of the entropy reduction that occurs when a Kondo singlet forms in a strongly coupled GaAs quantum dot, using temperature‑dependent ch…
20 Second Parity Lifetime in an InAs--Pb Tetron Device
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162
A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…
Topological Robustness of Anyon Tunneling at
Adithya Suresh, Ramon Guerrero-Suarez, Tanmay Maiti +4
The scaling exponent of the quasiparticle propagator for incompressible fractional quantum Hall states in the Laughlin sequence is expected to be robust against perturbations t…
Distinct Lifetimes for and Loop Measurements in a Majorana Tetron Device
Morteza Aghaee, Zulfi Alam, Rikke Andersen +164
We present a hardware realization and measurements of a tetron qubit device in a superconductor-semiconductor heterostructure. The device architecture contains two parallel superco…
Single electron interference and capacitive edge mode coupling generates flux periodicity in Fabry-Perot interferometers
Shuang Liang, James Nakamura, Geoffrey C. Gardner +1
Experimental observations of flux periodicity , where , for interference of the outermost edge mode in the integer quantum Hall regime have been attributed to a…
