Transmission based tomography for spin qubits
Amritesh Sharma, Ashwin A. Tulapurkar
We consider a system of static spin qubits embedded in a one-dimensional spin coherent channel and develop a scheme to readout the state of one and two qubits separately. We use un…

Generation of n-qubit W states using Spin Torque
Amritesh Sharma, Ashwin A. Tulapurkar
We examine here a scheme to generate a W state of an n-qubit system with all-to-all pairwise exchange interaction between n qubits. This relies on sharing of superposed excitations…
