Optimization by decoded quantum interferometry
NP-hardness results indicate that finding exact optima and even sufficiently good approximate optima for worst-case instances of many…
Classical theories of gravity produce entanglement
To illustrate this further, we now demonstrate how equation (4) leads to entanglement in a version of Feynman’s…
‘Squeezed light’ might be the secret to building the quantum internet
Imagine a future where the internet isn’t just fast, it’s fundamentally different. Where information doesn’t travel through cables…
