Quantum Prisoners' Dilemma under Enhanced Interrogation
George Siopsis, Radhakrishnan Balu, Neal Solmeyer
In the quantum version of prisoners' dilemma, each prisoner is equipped with a single qubit that the interrogator can entangle. We enlarge the available Hilbert space by introducin…
Bounds on the dynamics of periodic quantum walks and emergence of the gapless and gapped Dirac equation
N. Pradeep Kumar, Radhakrishna Balu, Raymond Laflamme +1
We study the dynamics of discrete-time quantum walk using quantum coin operations, and in time-dependent periodic sequence. For the two-period quantum…
Physical realization of topological quantum walks on IBM-Q and beyond
Radhakrishnan Balu, Daniel Castillo, George Siopsis
We discuss an efficient physical realization of topological quantum walks on a finite lattice. The -point lattice is realized with qubits, and the quantum circuit uti…
Quantum routing games
Neal Solmeyer, Ricky Dixon, Radhakrishnan Balu
We discuss the connection between a class of distributed quantum games, with remotely located players, to the counter intuitive Braess' paradox of traffic flow that is an important…
Fermi's golden rule, the origin and breakdown of Markovian master equations, and the relationship between oscillator baths and the random matrix model
Siddhartha Santra, Benjamin Cruikshank, Radhakrishnan Balu +1
Fermi's golden rule applies to a situation in which a single quantum state is coupled to a near-continuum. This "quasi-continuum coupling" structure results in a rate e…
Characterizing the Nash equilibria of three-player Bayesian quantum games
Neal Solmeyer, Radhakrishnan Balu
Quantum games with incomplete information can be studied within a Bayesian framework. We analyze games quantized within the EWL framework [Eisert, Wilkens, and Lewenstein, Phys Rev…
Characterizing the Nash equilibria of a three-player Bayesian quantum game
Neal Solmeyer, Ricky Dixon, Radhakrishnan Balu
Quantum games with incomplete information can be studied within a Bayesian framework. We consider a version of prisoner's dilemma (PD) in this framework with three players and char…
Probability distributions for Markov chains based quantum walks
Radhakrishnan Balu, Chaobin Liu, Salvador E. Venegas-Andraca
We analyze the probability distributions of the quantum walks induced from Markov chains by Szegedy (2004). The first part of this paper is devoted to the quantum walks induced fro…
