Current fluctuations in a non-additive open quantum system: breakdown of the quantum-jump approach
Ilia Khomchenko, Saulo V. Moreira, Emanuel Schwarzhans +2
Open quantum system dynamics is efficiently described by the quantum master equation formalism. Therein, quantum master equations in Lindblad form constitute an important subclass…
Structured Parameterization and Non-Stabilizerness in Hypergraph QAOA
Evan Camilleri, André Xuereb, Tony J. G. Apollaro +1
The quantum approximate optimization algorithm (QAOA) has emerged as a promising candidate for demonstrating quantum advantage on noisy intermediate-scale quantum (NISQ) devices. W…
Approaching the Limit of Quantum Clock Precision
Chad Nelmes, Emanuel Schwarzhans, Tony Apollaro +2
Precise and autonomous clocks are of fundamental interest and central importance to both foundational studies and practical applications. Here, we construct a blueprint for a quant…
Variational Gibbs State Preparation on Trapped-Ion Devices
Reece Robertson, Mirko Consiglio, Josey Stevens +3
We implement a variational quantum algorithm for Gibbs state preparation of a transverse-field Ising model on IonQ's quantum computers. To this end, we train the variational parame…
Achieving fast and robust perfect entangling gates via reinforcement learning
Leander Grech, Matthias G. Krauss, Mirko Consiglio +4
Noisy intermediate-scale quantum computers hold the promise of tackling complex and otherwise intractable computational challenges through the massive parallelism offered by qubits…
Memory effects in repeated uses of quantum channels
Hayden Zammit, Roberto Salazar, Gianluca Valentino +2
Quantum Information Processing (QIP) tasks can be efficiently formulated in terms of quantum dynamical maps, whose formalism is able to provide the appropriate mathematical represe…
