Encoding a qubit in logical quantum states with wavefunctions characterized by disjoint support and robust energies can ...

Circuit quantization links a physical circuit to its corresponding quantum Hamiltonian. The standard quantization proced...

In a new PRA manuscript, we present a gradient-based optimal-control technique for open quantum systems that utilizes qu...

In a new collaboration with the Université de Sherbrooke, we have shown that the coherence times of a realistic 0–π ...

In a recent arXiv preprint, we present a gradient-based optimal-control technique for open quantum systems that utilizes...
