... A quantum computer taps directly into the fundamental fabric of reality – the strange and counter-intuitive world of quantum mechanics – to speed computation. Rather than store information as 0s or 1s as conventional computers do, a quantum computer uses qubits – which can be 1 or 0 or both at the s ...

There are three types of processes: • quasistatic process: it occurs very slowly in time • reversible process: a quasistatic process that can be reversed without changing the system or the environment. The system may always be consi ...
