A protected vortex exciton qubit
Suvabrata De, Tim Spiller
We propose a protected qubit which is `dual' to a suggestion of a superconducting current mirror qubit [A. Kitaev, arXiv:0609441 (2006)]. Our construction can be regarded as the ma…
Detection of Chern numbers and entanglement in topological two-species systems through subsystem winding numbers
James de Lisle, Suvabrata De, Emilio Alba +4
Topological invariants, such as the Chern number, characterise topological phases of matter. Here we provide a method to detect Chern numbers in systems with two distinct species o…
Cooling atom-cavity systems into entangled states
J. Busch, S. De, S. S. Ivanov +3
Generating entanglement by simply cooling a system into a stationary state which is highly entangled has many advantages. Schemes based on this idea are robust against parameter fl…
Ancilla-based quantum simulation
Katherine L. Brown, Suvabrata De, Vivien M. Kendon +1
We consider simulating the BCS Hamiltonian, a model of low temperature superconductivity, on a quantum computer. In particular we consider conducting the simulation on the qubus qu…
