Realizing the Petz Recovery Map on an NMR Quantum Processor
Gayatri Singh, Ram Sagar Sahani, Vinayak Jagadish +3
The Petz recovery map is a central construct in quantum information theory, providing an explicit, channel-aware prescription for reversing the effects of noise. Unlike standard qu…
Simulating Three-Flavor Neutrino Oscillations on an NMR Quantum Processor
Gayatri Singh, Arvind, Kavita Dorai
Neutrino oscillations can be efficiently simulated on a quantum computer using the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) theory in close analogy to the physical processes realized…
Experimental decoherence mitigation using a weak measurement-based scheme and the duality quantum algorithm
Gayatri Singh, Akshay Gaikwad, Arvind +1
We experimentally demonstrate a weak measurement and measurement reversal-based scheme to ameliorate the effects of decoherence due to amplitude damping, on an NMR quantum processo…
Using linear and nonlinear entanglement witnesses to generate and detect bound entangled states on an IBM quantum processor
Vaishali Gulati, Gayatri Singh, Kavita Dorai
We investigate bound entanglement in three-qubit mixed states which are diagonal in the Greenberger-Horne-Zeilinger (GHZ) basis. Entanglement in these states is detected using enta…
Experimental quantum state transfer of an arbitrary single-qubit state on a cycle with four vertices using a coined quantum random walk
Gayatri Singh, Kavita Dorai, Arvind
We experimentally demonstrate the transfer of an unknown single-qubit state from Alice to Bob via a two-step discrete-time quantum random walk on a cycle with four vertices on a fo…
Direct tomography of quantum states and processes via weak measurements of Pauli spin operators on an NMR quantum processor
Akshay Gaikwad, Gayatri Singh, Kavita Dorai +1
In this paper, we present an efficient weak measurement-based scheme for direct quantum state tomography (DQST) and direct quantum process tomography (DQPT), and experimentally imp…
