  • Probing quantum many-body systems while undergoing thermalisation is challenging, especially when looking for signatures of ergodicity and quantum chaos. Here, the authors study a lattice gauge theory in 2+1 dimensions using a trapped-ion-based universal digital quantum computer, unveiling the role of entanglement in the thermalization dynamics.

  • Generation of entanglement in quantum computers stems from the native interactions between qubits, which are usually restricted to the pairwise limit. A method to control three- and four-body interactions has now been demonstrated with trapped ions.

  • A one-dimensional trapped-ion quantum simulator with up to 23 spins is used to demonstrate a continuous symmetry-breaking phase that relies on long-range interactions.

  • Being able to perform qubit measurements within a quantum circuit and adapt to their outcome broadens the power of quantum computers. These mid-circuit measurements have now been used to implement a cryptographic proof of non-classical behaviour.

  • Many-body open quantum systems are predicted to undergo a phase transition towards a pure state through frequent projective measurements. The phases separated by this transition have now been observed with random circuits on a trapped-ion computer.
