We show that relatively simple integrated photonic circuits have the potential to realize a high fidelity deterministic controlled-phase gate between photonic qubits using bulk optical …
Photonic entanglement swapping, the procedure of entangling photons without any direct interaction, is a fundamental test of quantum mechanics and an essential resource to the …
A random access memory (RAM) uses n bits to randomly address N = 2 n distinct memory cells. A quantum random access memory (QRAM) uses n qubits to address any quantum …
Non-Abelian gauge theories underlie our understanding of fundamental forces in nature, and developing tailored quantum hardware and algorithms to simulate them is an outstanding …
The quantum capacity of a quantum channel captures its capability for noiseless quantum communication. It lies at the heart of quantum information theory. Unfortunately, our poor …
Background: Previous works highlight the neurocognitive differences between apathetic and disinhibited clinical presentations of the behavioral variant frontotemporal dementia (bvFTD)…
Measurement-device-independent quantum key distribution (MDI-QKD) can eliminate all detector side channels and it is practical with current technology. Previous implementations of …
A plot of the corrected rate is shown in Fig. 1 along with the rate from the published Letter for comparison. At a distance of 1000 km, the corrected rate is lower by a factor of 95, leading …
Operators and service companies are considering alternative methods to remedy shortage of qualified and experienced staff to manage increasing activity and complexity. TNK-BP's …
We consider the problem of discriminating two different quantum states in the setting of asymptotically many copies, and determine the minimal probability of error. This leads to the …
