Evolution of two-mode quantum states under a dissipative environment: which quantum resource survives better, squeezing or entanglement?

Rishabh, Chandan Kumar, Geetu Narang +1

We explore the relative robustness of squeezing and entanglement (which are quantum resources interconvertible via passive optics) for two-mode Gaussian states under different diss…

A comparative study of system size dependence of the effect of non-unitary channels on different classes of quantum states

Geetu Narang, Shruti Dogra, Arvind

We investigate the effect of different types of non-unitary quantum channels on multi-qubit quantum systems. For an -qubit system and a particular channel, in order to draw unbi…

Simulating a single qubit channel using a mixed state environment

Geetu Narang, Arvind

We analyze the class of single qubit channels with the environment modeled by a one-qubit mixed state. The set of affine transformations for this class of channels is computed anal…

Optical implementations, oracle equivalence, and the Bernstein-Vazirani algorithm

Arvind, Gurpreet Kaur, Geetu Narang

We describe a new implementation of the Bernstein-Vazirani algorithm which relies on the fact that the polarization states of classical light beams can be cloned. We explore the po…

Optimal asymmetric cloning machine on a great circle using no-signalling condition

Samir Kunkri, Md. Manirul Ali, Geetu Narang +1

Assuming the condition of no superluminal signalling, we got an upper bound on the quality of all asymmetric cloning machines, acting on qubits whose Bloch vectors lie on…
