Programmable quantum state discriminator by Nuclear Magnetic Resonance
T. Gopinath, Ranabir Das, Anil Kumar
In this paper a programmable quantum state discriminator is implemented by using nuclear magnetic resonance. We use a two qubit spin-1/2 system, one for the data qubit and one for…
Spectral implementation of some quantum algorithms by one- and two-dimensional nuclear magnetic resonance
Ranabir Das, Anil Kumar
Quantum information processing has been effectively demonstrated on a small number of qubits by nuclear magnetic resonance. An important subroutine in any computing is the readout…
Use of non-adiabatic geometric phase for quantum computing by nuclear magnetic resonance
Ranabir Das, S. K. Karthick Kumar, Anil Kumar
Geometric phases have stimulated researchers for its potential applications in many areas of science. One of them is fault-tolerant quantum computation. A preliminary requisite of…
Experimental implementation of local adiabatic evolution algorithms by an NMR quantum information processor
Avik Mitra, Arindam Ghosh, Ranabir Das +2
Quantum adiabatic algorithm is a method of solving computational problems by evolving the ground state of a slowly varying Hamiltonian. The technique uses evolution of the ground s…
Quantum information processing by NMR using a 5-qubit system formed by dipolar coupled spins in an oriented molecule
Ranabir Das, Rangeet Bhattacharyya, Anil Kumar
Quantum Information processing by NMR with small number of qubits is well established. Scaling to higher number of qubits is hindered by two major requirements (i) mutual coupling…
Quantum Information processing by NMR: Implementation of Inversion-on-equality gate, Parity gate and Fanout gate
T. Gopinath, Ranabir Das, Anil Kumar
While quantum information processing by nuclear magnetic resonance (NMR) with small number of qubits is well established, implementation of lengthy computations have proved to be d…
