Realizing the Kramers Qubit in Atomically Thin Semiconductors

Abstract

Long-lived quantum bits (qubits) are essential to reducing error-correction overheads in terms of reducing the number of physical qubits required to encode a single logical qubit. The so-called Kramers qubit promises to significantly enhance qubit lifetimes owing to spin-valley coupled basis states that are topologically protected from relaxation by time-reversal symmetry. This project aims to realize a Kramers qubit for spins confined to semiconducting transition metal dichalcogenide (TMDC) monolayers, promising qubit lifetimes exceeding tens of seconds.
