Spin–valley protected Kramers pair in bilayer graphene
The intrinsic valley degree of freedom makes bilayer graphene (BLG) a unique platform for semiconductor qubits. The single-carrier quantum dot (QD)…
Grover’s algorithm in a four-qubit silicon processor above the fault-tolerant threshold
Spin qubits in silicon are strong contenders for the realization of a practical quantum computer, having demonstrated single- and two-qubit gates w…
A real-time, scalable, fast and resource-efficient decoder for a quantum computer
The development of quantum computers will require the careful management of the noise effects associated with qubit performance. However, the decod…
Dynamical topology of chiral and nonreciprocal state transfers in a non-Hermitian quantum system
Topological phenomena are fundamentally underlain by the geometric phase of eigenstates. Time-varying Hamiltonians furthermore allow for a dynamica…
