The quantum computers of the future will work equally well with encrypted and unencrypted input

When future users of quantum computers need to analyze their data or run quantum algorithms, they will often have to send encrypted information to the computer. Because of this requirement, researchers from DTU Physics and the University of Toronto have investigated whether a quantum computer can work equally well with encrypted and unencrypted...

Continuous-variable quantum computing on encrypted data

When future users of quantum computers need to analyze their data or run quantum algorithms, they will often have to send encrypted information to the computer. Because of this requirement, researchers from DTU Physics and the University of Toronto have investigated whether a quantum computer can work equally well with encrypted and unencrypted...

Squeezed-light enhanced feedback cooling

In a recent proof-of-principle experiment, published in Nature Communications, researchers from DTU Physics have demonstrated how quantum-engineered states of light can enhance the efficiency of feedback cooling beyond the classical bounds in an optomechanical setting.

One step closer to secure Internet communication

Every day, most of us transmit personal data over the Internet. Secure communication is thus an absolute necessity. In a new article in Nature Photonics, researchers from DTU Physics show that quantum-encrypted signals can be sent via open transmission masts and still be 100 per cent secure, even if hackers listen in.
