Blockwise Key Distillation in Satellite-based Quantum Key Distribution
Minu J. Bae, Nitish K. Panigrahy, Prajit Dhara +4
Free-space satellite communication has significantly lower photon loss than terrestrial communication via optical fibers. Satellite-based quantum key distribution (QKD) leverages t…
Phonon-Induced Decoherence in Color-Center Qubits
Prajit Dhara, Saikat Guha
Electron spin states of solid-state defects such as Nitrogen- and Silicon-vacancy {\em color centers} in diamond are a leading quantum-memory candidate for quantum communications a…
Entangling Quantum Memories via Heralded Photonic Bell Measurement
Prajit Dhara, Dirk Englund, Saikat Guha
A common way to entangle quantum memories is via photonic entanglement swaps. Each of two memories, connected by an optical channel, emits a photonic qubit entangled with itself, a…
Exploring the possibility of a complex-valued non-Gaussianity measure for quantum states of light
Andrew J. Pizzimenti, Prajit Dhara, Zacharie Van Herstraeten +2
We consider a quantity that is the differential relative entropy between a generic Wigner function and a Gaussian one. We prove that said quantity is minimized with respect to its…
