Entropic costs of extracting classical ticks from a quantum clock
Vivek Wadhia, Florian Meier, Federico Fedele +12
We experimentally realize a quantum clock by using a charge sensor to count charges tunneling through a double quantum dot (DQD). Individual tunneling events are used as the clock'…
Many-body interferometry with semiconductor spins
Daniel Jirovec, Stefano Reale, Pablo Cova-Fariña +9
Quantum simulators enable studies of many-body phenomena which are intractable with classical hardware. Spins in devices based on semiconductor quantum dots promise precise electri…
Rapid optimal work extraction from a quantum-dot information engine
Kushagra Aggarwal, Alberto Rolandi, Yikai Yang +8
The conversion of thermal energy into work is usually more efficient in the slow-driving regime, where the power output is vanishingly small. Efficient work extraction for fast dri…
Mitigation of exchange cross-talk in dense quantum dot arrays
Daniel Jirovec, Pablo Cova Fariña, Stefano Reale +7
Coupled spins in semiconductor quantum dots are a versatile platform for quantum computing and simulations of complex many-body phenomena. However, on the path of scale-up, cross-t…
Site-resolved magnon and triplon dynamics on a programmable quantum dot spin ladder
Pablo Cova Fariña, Daniel Jirovec, Xin Zhang +7
Quasi-particle dynamics in interacting systems in the presence of disorder challenges the notion of internal thermalization, but proves difficult to investigate theoretically for l…
Exchange anisotropies in microwave-driven singlet-triplet qubits
Jaime Saez-Mollejo, Daniel Jirovec, Yona Schell +7
Hole spin qubits are rapidly emerging as the workhorse of semiconducting quantum processors because of their large spin-orbit interaction, enabling fast all-electric operations at…
