Observation of entangled states of a fully-controlled 20 qubit system

We generate and characterise entangled states of a register of 20 individually-controlled qubits, where each qubit is encoded into the electronic state of a trapped atomic ion. Entanglement is… Expand

Efficient tomography of a quantum many-body system

Traditionally quantum state tomography is used to characterize a quantum state, but it becomes exponentially hard with the system size. An alternative technique, matrix product state tomography, is… Expand
