The debate continues about quantum effects in the natural ‘compass sense’ that some birds have. The most well-studied species is the European Robin, shown in this picture:
We’ve just published a Comment in PRL, with our counter arguments to some of the claims in a recent Letter there. Read it here.

A quantum error-correcting code is a central piece of fault-tolerant quantum computation that is required to realise large-scale quantum algorithms. Unfortunately, the state-of-the-art codes with the best parameters that require the least overheads do not Read more…
The most promising class of algorithms for near-term quantum computers are variational quantum algorithms (VQAs), where a parametrised circuit of quantum gates calculates some cost function, which is then optimised to produce the solution to Read more…
A promising approach to build a scalable quantum computer is to manufacture a large array of qubits on a chip. This is common to several hardware architectures including superconducting qubits and spin-qubits in silicon. The Read more…
