Towards the simulation of transition-metal oxides of the cathode battery materials using VQE methods
Marwa H. Farag, Joydip Ghosh
Variational quantum eigensolver (VQE) is a hybrid quantum-classical technique that leverages noisy intermediate scale quantum (NISQ) hardware to obtain the minimum eigenvalue of a…
High-Fidelity Single-Shot Toffoli Gate via Quantum Control
Ehsan Zahedinejad, Joydip Ghosh, Barry C. Sanders
A single-shot Toffoli, or controlled-controlled-NOT, gate is desirable for classical and quantum information processing. The Toffoli gate alone is universal for reversible computin…
Emulating quantum state transfer through a spin-1 chain on a 1D lattice of superconducting qutrits
Joydip Ghosh
Spin-1 systems, in comparison to spin-1/2 systems, offer a better security for encoding and transfer of quantum information, primarily due to their larger Hilbert spaces. Supercond…
A leakage-resilient approach to fault-tolerant quantum computing with superconducting elements
Joydip Ghosh, Austin G. Fowler
Superconducting qubits, while promising for scalability and long coherence times, contain more than two energy levels, and therefore are susceptible to errors generated by the leak…
Controlled-NOT gate with weakly coupled qubits: Dependence of fidelity on the form of interaction
Joydip Ghosh, Michael R. Geller
An approach to the construction of the CNOT quantum logic gate for a 4-dimensional coupled-qubit model with weak but otherwise arbitrary coupling has been given recently [M. R. Gel…
