Analytical controls for dispersive multi-qubit interactions in mediator-coupled quantum registers
Bora Baran, Tommaso Calarco, James O'Sullivan +2
Fast control of long-lived quantum registers often relies on an auxiliary degree of freedom, a mediator, but real mediator excitation can introduce decoherence, leakage, or loss wh…

Interaction-resolved decomposition of multi-qubit unitaries via computational-basis phases
Bora Baran, Tommaso Calarco, Matthias M. Mueller +1
In multi-qubit quantum control, target unitary operations are commonly specified through full-unitary target descriptions and assessed through global comparison measures. In this w…

Heisenberg-Limited Quantum Hamiltonian Learning via Randomly Spread Product-States
Bora Baran, Timothy Heightman
We show how the Heisenberg-limited quadratic Fisher-information regime of short-time quantum evolution can be made practically accessible for quantum Hamiltonian learning, using on…
