Nothing is stronger than quantum connections – and now we know why

The mathematics of graphs has helped reveal a principle that limits the strength of quantum correlations – and explains why physicists have never measured any stronger connections in some post-quantum realm

Liquid Gold Anna Curran Department of Mathematics A lattice of bubbles inside a ring that has been dipped in soapy water. The bubbles hold their shape because of molecules in the dish soap called surfactants, which stabilise the interface. Surfactants are all around us - for example, they allow soap to break down dirt and bacteria, and they are given to premature babies to help them inflate their lungs. Conversely, they threaten the efficacy of various industrial applications such as self-cleaning surfaces and laptop cooling systems. My research focuses on mathematically modelling the effect of these molecules at a f luid interface, in order to gain a greater understanding of how to control their behaviour in these applications.

Quantum computer circuitry illustration. Conventional computers store information as 'bits', with each transistor holding either a 1 or a 0. Quantum computers use quantum bits, or qubits, which operate according to two principles of quantum physics. One of the principles, supposition, allows a qubit to store a 1 and a 0 at the same time. This means two qubits can hold four values at once. The second principle, entanglement, means that the state of one qubit can depend on the state of another. As you expand the number of qubits, the machine becomes exponentially more powerful.
