Wigner's Theorem for stabilizer states and quantum designs

Valentin Obst, Arne Heimendahl, Tanmay Singal +1

We describe the symmetry group of the stabilizer polytope for any number of systems and any prime local dimension . In the qubit case, the symmetry group coincides with the…

Counting stabiliser codes for arbitrary dimension

Tanmay Singal, Che Chiang, Eugene Hsu +3

In this work, we compute the number of stabilizer codes made up of -dimensional qudits, for arbitrary positive integers . In a seminal work by Gross (Ref. [23]) t…

One parameter generalization of BW inequality and its application to open quantum dynamics

Dariusz Chruściński, Gen Kimura, Hiromichi Ohno +1

In this paper, we introduce a one parameter generalization of the famous Böttcher-Wenzel (BW) inequality in terms of a -deformed commutator. For matrices and $B…

Approximate 3-designs and partial decomposition of the Clifford group representation using transvections

Tanmay Singal, Min-Hsiu Hsieh

We study a scheme to implement an asymptotic unitary 3-design. The scheme implements a random Pauli once followed by the implementation of a random transvection Clifford by using s…

Implementation of quantum measurements using classical resources and only a single ancillary qubit

Tanmay Singal, Filip B. Maciejewski, Michał Oszmaniec

We propose a scheme to implement general quantum measurements, also known as Positive Operator Valued Measures (POVMs) in dimension using only classical resources and a single…

Single-Copy Certification of Two-Qubit Gates without Entanglement

Yujun Choi, Tanmay Singal, Young-Wook Cho +5

A quantum state transformation can be generally approximated by single- and two-qubit gates. This, however, does not hold with noisy intermediate-scale quantum technologies due to…

A Structure of Minimum Error Discrimination for Linearly Independent States

Tanmay Singal, Eunsang Kim, Sibasish Ghosh

In this paper we study the Minimum Error Discrimination problem (MED) for ensembles of linearly independent (LI) states. We define a bijective map from the set of those ensembles t…

Detecting Noisy Channels by Channel Discrimination : Local versus Entangled Resources

Joonwoo Bae, Tanmay Singal

Dynamics of many-qubit systems, that may correspond to computational processing with quantum systems, can be efficiently and generally approximated by a sequence of two- and single…

Preserving Measurements for Optimal State Discrimination over Quantum Channels

Spiros Kechrimparis, Tanmay Singal, Chahan M. Kropf +1

In this work, we consider optimal state discrimination for a quantum system that interacts with an environment, i.e., states evolve under a quantum channel. We show the conditions…

Framework for distinguishability of orthogonal bipartite states by one-way local operations and classical communication

Tanmay Singal

In the topic of perfect local distinguishability of orthogonal multipartite quantum states, most results obtained so far pertain to bipartite systems whose subsystems are of specif…

Necessary Condition for Local Distinguishability of Maximally Entangled States: Beyond Orthogonality Preservation

Tanmay Singal, Ramij Rahman, Sibasish Ghosh +1

The (im)possibility of local distinguishability of orthogonal multipartite quantum states still remains an intriguing question. Beyond , the pr…

Minimum Error Discrimination for an Ensemble of Linearly Independent Pure States

Tanmay Singal, Sibasish Ghosh

Inspired by the work done by Belavkin [Belavkin V. P., Stochastics, 1, 315 (1975)], and independently by Mochon, [Phys. Rev. A 73, 032328, (2006)], we formulate the problem of mini…

Is Interstellar travel to an exoplanet Possible?

Tanmay Singal, Ashok K. Singal

It is shown that space travel, even in the most distant future, will remain confined to our own planetary system, and a similar conclusion will hold forth for any other civilizatio…
