The UK Ministry of Defence (MoD) has acquired the government's first quantum computer.
Quantum computers are able to make very complex calculations extremely quickly and their creators say they can solve the problems regular computers cannot.
The MoD will work with British company Orca Computing to explore applications for quantum technology in defence.
Stephen Till, of the MoD's Defence Science and Technology Laboratory (DSTL), called it a "milestone moment".
The computers found in most of our homes and workplaces process data in bits, which have a binary value of either zero or one.
Quantum computers instead use a two-state unit for data processing called a qubit.
This can represent digits like one or zero simultaneously through a quantum mechanical process called superposition, letting quantum computers bridge binary digits and cope with uncertainty where regular computers cannot.
