New questions about many queries for quantum computing

Bucket brigade scheme for a qRAM with eight memory locations.

One of the tasks that quantum computing promises is algorithmic speedups over classical computing for certain types of problems – one of which is quantum searching. To achieve this, it’s important to build a robust quantum memory, more specifically, a memory that can store information which can be addressed quantum mechanically.

Quantum key distribution gets ready for satellite uplinks

Moving receiver mounted on a truck

University of Waterloo researchers performed a lab demonstration proving the feasibility of Quantum Key Distribution over a satellite uplink.

In an emulated environment for performing QKD, a team of researchers analyzed the impact of the optical loss that occurs between the photon source and the satellite receiver. They successfully generated a secure key using algorithms tailored for a satellite receiver, an important step towards extending the distance of ultra-secure communications.
