The theory of epochal time states that the genesis of an actual occasion does not take place in physical (clock) time; it creates a quantum of physical time: in every act of becoming there is the becoming of something with temporal extension; but that act itself is not extensive, in the sense that it is divisible into earlier and later acts of becoming which correspond to the extensive divisibility of what has become» (PR 69/107).

However, that simple quantum state persisted for just 5 nanoseconds, too little time to put the device into more complex quantum states of motion.

The researchers probed this memory through a process called quantum tomography — meaning that they repeated the experiment many times and cataloged the state of the memory.

For example, she says, they might try to put the resonator into a Schrödinger cat state, in which it would contain a macroscopic sound wave, comprising many vibrational quanta, and at the same time be devoid of vibrations.

Moreover, the model can be generalized to add another path toward the solution of complex classical computational problems by taking advantage of quantum mechanical parallelism — the fact that, according to quantum mechanics, a system can be in many classical states at the same time.

In a quantum computer the 0 and 1 states can simultaneously exist, allowing a kind of parallel computation in which a large number of computational states are acted upon by the machine at the same time.
