Continuous-variable quantum key distribution (QKD) utilizes an ensemble of coherent states of light to distribute secret encryption keys between two parties in the presence of an eavesdropper (Left). The effect of reconciliation efficiency on the asymptotic secure key rate between distant parties. We proposed some MET-LDPC codes with low FER and high efficiency $\beta$ to obtain a maximum possible secure key rate (Right)

Quantum computer’s ability to optimize stock portfolio tested

In collaboration with the consulting firm KPMG, a student from DTU Physics has tested whether a quantum computer is better at optimizing a stock portfolio than a conventional...

Peeking into the quantum random number generator developed at DTU physics reveals a lot of seemingly ordinary optics and electronics. But together, the components form s high-speed and ultra-secure source of true randomness, enabled by quantum physics.

High-speed quantum random number generator secure against quantum attacks

At first glance, random numbers may seem trivial to produce and utterly useless. Not an easy sell. Isn’t it just a matter of flipping a coin? Not quite!
