JQ Manual

Quick Overview

For quick start, please note 3 text input. We we will name the 1st, 2nd and 3rd -- from left to right. Please also note 2 buttons: Run and Load.

1st text input - init state

You enter init state of qubits here. Decimal integer is required here. Its binary representation defines start states of qubits. **Qubit 0 is on the top**.

2nd text input - qubit signature

You enter list of integers here in the following format: [qubit1, qubit2, ..., qubitn]. This bit signature is used for displaying probabilities.

Assume you entered there [3,4] and assume that list of probabilies is like the following:

01 : 0.3 (1)
10 : 0.7 (2)

It simply means that a lot of hypothetical measurements would show that Prob(qubit 4 is in state 0 AND qubit 3 is in state 1) = 0.3 and Prob(qubit 4 is in state 1 AND qubit 3 is in state 0) = 0.7.

Formally, this is a list of integers with given probability. The n-th bit of chosen integer (from right) represents the state of n-th quibit in qubit signature (from left) after hypothetical measurment. Note that you have these integer in binary and in decimal in ().
