Dynamical decoupling and quantum error correction with SU(d) symmetries
Colin Read, Eduardo Serrano-Ensástiga, John Martin
Dynamical decoupling is a long-established and effective way to suppress unwanted interactions in qubit systems, enabling advances in fields ranging from quantum metrology to quant…
Coherent Generation and Protection of Anticoherent Spin States
Jérôme Denis, Colin Read, John Martin
We report the first protocol specifically designed to generate anticoherent spin- states at different orders. The protocol consists of cycles of a rotation pulse about an axis f…
Dynamical decoupling of interacting spins through group factorization
Colin Read, Eduardo Serrano-Ensástiga, John Martin
Dynamical decoupling (DD) is a well-known open-loop protocol for suppressing unwanted interactions in a quantum system, thereby drastically extending the coherence time of useful q…
Platonic dynamical decoupling sequences for interacting spin systems
Colin Read, Eduardo Serrano-Ensástiga, John Martin
In the NISQ era, where quantum information processing is hindered by the decoherence and dissipation of elementary quantum systems, developing new protocols to extend the lifetime…
