Measure of not-completely-positive qubit maps: the general case
Vinayak Jagadish, R. Srikanth, Francesco Petruccione
We show that the set of not-completely-positive (NCP) maps is unbounded, unless further assumptions are made. This is done by first proposing a reasonable definition of a valid NCP…
Non-Markovian Dynamics of Discrete-Time Quantum Walks
Subhashish Banerjee, N. Pradeep Kumar, R. Srikanth +2
In the case of the discrete time coined quantum walk the reduced dynamics of the coin shows non-Markovian recurrence features due to information back-flow from the position degree…
The qubit reveals a qubit-cavity system
Sreenath K. Manikandan, Vinayak Jagadish, Anil Shaji
We show that the coupling between a qubit and a single mode cavity can be estimated from the process tomography data for the qubit alone. All the parameters of the coupling Hamilto…
