Control of Majorana Edge Modes by a g-factor Engineered Nanowire Spin Transistor
Amrit De, Alexey A. Kovalev
We propose the manipulation of Majorana edge states via hybridization and spin currents in a nanowire spin transistor. The spin transistor is based on a heterostructure nanowire co…
Dynamically corrected gates for qubits with always-on Ising couplings: Error model and fault-tolerance with the toric code
Amrit De, Leonid P. Pryadko
We describe how a universal set of dynamically-corrected quantum gates can be implemented using sequences of shaped decoupling pulses on any qubit network forming a sparse bipartit…
A Couped-Qubit Tavis Cummings Scheme for Prolonging Quantum Coherence
Amrit De
Qubit-qubit interactions can significantly boost quantum coherence times for Bell states. The coherence-time-enhancements are however not monotonic and there exists a phase where f…
Spin Transfer of Quantum Information between Majorana Modes and a Resonator
Alexey A. Kovalev, Amrit De, Kirill Shtengel
We show that resonant coupling and entanglement between a mechanical resonator and majorana bound states can be achieved via spin currents in a 1D quantum wire with strong spin-orb…
Continuous third harmonic generation in a terahertz driven modulated nanowire
Kathleen E. Hamilton, Alexey A. Kovalev, Amrit De +1
We consider the possibility of observing continuous third-harmonic generation using a strongly driven, single-band one-dimensional metal. In the absence of scattering, the quantum…
