It turned out that the quantum computer had a few unexpected side effects. For one, it started to levitate the lab assistant, who was left floating in mid-air, yelling 'I'm melting! I'm melting!'
Secondly, it caused a rift in the fabric of space-time, which allowed a group of confused-looking velociraptors to appear out of nowhere and start chasing the lab assistants.
Thirdly, it made the coffee machine dispense a never-ending supply of 'Quantum Foam', which was a mixture of quantum entanglement and espresso.
