Perturbative 2-body Parent Hamiltonians for Projected Entangled Pair States
Courtney G. Brell, Stephen D. Bartlett, Andrew C. Doherty
We construct parent Hamiltonians involving only local 2-body interactions for a broad class of Projected Entangled Pair States (PEPS). Making use of perturbation gadget techniques,…
Suppressing qubit dephasing using real-time Hamiltonian estimation
Michael D. Shulman, Shannon P. Harvey, John M. Nichol +4
Unwanted interaction between a quantum system and its fluctuating environment leads to decoherence and is the primary obstacle to establishing a scalable quantum information proces…
Exchange-based two-qubit gate for singlet-triplet qubits
Matthew P. Wardrop, Andrew C. Doherty
We analyse a simple exchange-based two-qubit gate for singlet-triplet qubits in gate-defined semiconductor quantum dots that can be implemented in a single exchange pulse. Excitati…
