Quantum mechanics could explain why DNA can spontaneously mutate

The molecules of life, DNA, replicate with astounding precision, yet this process is not immune to mistakes and can lead to mutations. Using sophisticated computer modeling, a team of physicists and chemists at the University ...

New theory explains mystery behind fast magnetic reconnection

When magnetic field lines of opposite directions merge, they create explosions that can release massive amounts of energy. On the sun, the merging of opposing field lines causes solar flares and coronal mass ejections, giant ...

Fault-tolerant quantum computer memory in diamond

Quantum computing holds the potential to be a game-changing future technology in fields ranging from chemistry to cryptography to finance to pharmaceuticals. Compared to conventional computers, scientists suggest that quantum ...

Scientists simulate 'fingerprint' of noise on quantum computer

For humans, background noise is generally just a minor irritant. But for quantum computers, which are very sensitive, it can be a death knell for computations. And because "noise" for a quantum computer increases as the computer ...

Flawed diamonds may provide perfect interface for quantum computers

Flaws in diamonds—atomic defects where carbon is replaced by nitrogen or another element—may offer a close-to-perfect interface for quantum computing, a proposed communications exchange that promises to be faster and ...

In the quantum realm, not even time flows as you might expect

A team of physicists at the Universities of Bristol, Vienna, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) has shown how quantum systems can simultaneously evolve along two ...
