Realizable receivers for discriminating arbitrary coherent-state waveforms and multi-copy quantum states near the quantum limit
Ranjith Nair, Saikat Guha, Si-Hui Tan
Coherent states of light, and methods for distinguishing between them, are central to all applications of laser light. We obtain the ultimate quantum limit on the error probability…
Achieving minimum-error discrimination of an arbitrary set of laser-light pulses
Marcus P. da Silva, Saikat Guha, Zachary Dutton
Laser light is widely used for communication and sensing applications, so the optimal discrimination of coherent states--the quantum states of light emitted by a laser--has immense…
Capacity of optical reading, Part 1: Reading boundless error-free bits using a single photon
Saikat Guha, Jeffrey H. Shapiro
We show that nature imposes no fundamental upper limit to the number of information bits per expended photon that can, in principle, be read reliably when classical data is encoded…
Information trade-offs for optical quantum communication
Mark M. Wilde, Patrick Hayden, Saikat Guha
Recent work has precisely characterized the achievable trade-offs between three key information processing tasks---classical communication (generation or consumption), quantum comm…
Symmetric M-ary phase discrimination using quantum-optical probe states
Ranjith Nair, Brent J. Yen, Saikat Guha +2
We present a theoretical study of minimum error probability discrimination, using quantum- optical probe states, of M optical phase shifts situated symmetrically on the unit circle…
Performance of polar codes for quantum and private classical communication
Zachary Dutton, Saikat Guha, Mark M. Wilde
We analyze the practical performance of quantum polar codes, by computing rigorous bounds on block error probability and by numerically simulating them. We evaluate our bounds for…
