Matrix manipulations via unitary transformations and ancilla-state measurements
Alexander I. Zenchuk, Wentao Qi, Asutosh Kumar +1
We propose protocols for calculating inner product, matrix addition and matrix multiplication based on multiqubit Toffoli-type and the simplest one-qubit operations and employ anci…
Dilation, Discrimination and Uhlmann's Theorem of Link Products of Quantum Channels
Qiang Lei, Liuheng Cao, Asutosh Kumar +1
The study of quantum channels is the most fundamental theoretical problem in quantum information and quantum communication theory. The link product theory of quantum channels is an…
Efficient quantum compression for identically prepared states with arbitrary dimensio
Zeyu Chen, Chunhe Xiong, Kamil Khadiev +1
Identical preparation creates permutation symmetry that can be used for lossless quantum compression. For copies of an unknown -dimensional pure state, the tensor-power inpu…
Entanglement and Teleportation in a 1-D Network with Repeaters
Ganesh Mylavarapu, Indranil Chakrabarty, Kaushiki Mukherjee +2
The most simplest form of quantum network is an one dimensional quantum network with a single player in each node. In remote entanglement distribution each of the players carry out…
Quantum Algorithms for the Shortest Common Superstring and Text Assembling Problems
Kamil Khadiev, Carlos Manuel Bosch Machado, Zeyu Chen +1
In this paper, we consider two versions of the Text Assembling problem. We are given a sequence of strings of total length that is a dictionary, and a string $t…
Entanglement as the cross-symmetric part of quantum discord
Chunhe Xiong, Sunho Kim, Asutosh Kumar +3
In this paper, we show that the minimal quantum discord over "cross-symmetric" state extensions is an entanglement monotone. In particular, we show that the minimal Bures distance…
