jQ has an additional advanced feature — Hidden Console. When you place the cursor in the last line of the black window in the left you can enter some special directives.
 +
Bellow you will find a full list of Hidden Console directives:
 +
 +
=== clr() ===
 +
 +
Clears window.
 +
 +
===load()===
 +
 +
The same as button Load.
 +
 +
=== measure(bit) ===
 +
 +
Performs a measurement on a chosen bit. To see the result, you need to type '''<nowiki>prob([[bit]])</nowiki>'''. Changes the qregister state.
 +
 +
=== prob([signature<sub>1</sub>, signature<sub>2</sub>, ..., signature<sub>n</sub>]) ===
 +
 +
Displays the states of chosen qubits with probabilities after a series of hypothetical measurements. Doesn't change the qregister state. The value of state is binary grouped. Each group is defined by corresponding signature.
 +
Consider following example. Assume that the qregister state is:
 +
 +
<pre>
 +
(0.5,0)|0>
 +
(0.5,0)|1>
 +
(0.5,0)|4>
 +
(0.5,0)|5>
 +
</pre>
 +
 +
The corresponding probabilities are:
 +
 +
<pre>
 +
000 : 0.25 (0)
 +
001 : 0.25 (1)
 +
100 : 0.25 (4)
 +
101 : 0.25 (5)
 +
</pre>
 +
 +
After typing in Hidden Console '''prob( [ [0], [1,2] ] )'''
 +
 +
You will see the same result in different representation:

Contents

[edit] Quick Overview

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

[edit] 1st input - init state

1st.png You enter the init state of qubits here. A decimal integer is required here. Its binary representation defines the start states of the qubits in qregister. Qubit 0 is at the top.

[edit] 2nd input - qubit signature

2nd.png You enter a list of integers here in the following format: [qubit1, qubit2, ..., qubitn]. This qubit signature is used for displaying probabilities.

Suppose you have entered [3,4] and that the list of probabilities is: 

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, the result is a list of integers with a given probability. The n-th bit of the chosen integer (from the right) represents the state of the qubit which is listed as n-th in the qubit signature (from the left) after the hypothetical measurement. Note these integers are given in binary and in decimal in ().

The same result for the signature [4,3] would obviously be 

01 : 0.7 (1)
10 : 0.3 (2)

[edit] 3rd input - quantum circuit

3rd.png

You enter a list of quantum gates here in the following format [gate1, gate2, ..., gaten]. You can also add measurements to this list, they are represented by M(.).

[edit] Run Button

OK, after you've entered the initial state (if you don't, the default state is 0) and quantum circuit, you press the Run button, which applies the quantum circuit to the qregister and displays the end state and probabilities after a hypothetical measurement of the qubits listed in qubit signature (2nd input). For example: 

01 : 0.5 (1)
10 : 0.5 (2)

(0.707106781187,0)|1>
(0.707106781187,0)|2>

The first list shows the probabilities described in 2nd input - qubit signature section. The second list is just a state of the qregister (a complex vector).

[edit] Load Button

When you create some more complex and long circuit, you want to have it in a saved text file. You can. Write your circuit in a text file using your favorite editor, save it on your drive and then just press Load to load it into the Quantum Simulator.

Doesn't work under IE, so please use some other browser for this feature.

[edit] Hidden Console

Console.png

jQ has an additional advanced feature — Hidden Console. When you place the cursor in the last line of the black window in the left you can enter some special directives. Bellow you will find a full list of Hidden Console directives:

[edit] clr()

Clears window.

[edit] load()

The same as button Load.

[edit] measure(bit)

Performs a measurement on a chosen bit. To see the result, you need to type prob([[bit]]). Changes the qregister state.

[edit] prob([signature1, signature2, ..., signaturen])

Displays the states of chosen qubits with probabilities after a series of hypothetical measurements. Doesn't change the qregister state. The value of state is binary grouped. Each group is defined by corresponding signature. Consider following example. Assume that the qregister state is: 

(0.5,0)|0>
(0.5,0)|1>
(0.5,0)|4>
(0.5,0)|5>

The corresponding probabilities are: 

000 : 0.25 (0)
001 : 0.25 (1)
100 : 0.25 (4)
101 : 0.25 (5)

After typing in Hidden Console prob( [ [0], [1,2] ] )

You will see the same result in different representation: 

|0>|0>:0.25
|0>|1>:0.25
|2>|0>:0.25
|2>|1>:0.25

For prob( [ [0,1], [2] ]): 

|0>|0>:0.25
|0>|1>:0.25
|1>|0>:0.25
|1>|1>:0.25

[edit] reset(n)

Set the initial state of qregister to n.

[edit] run()

The same as the Run button.

[edit] state()

Displays current state (complex vector) of qregister.

[edit] version()

Displays current version of jQ.

[edit] Embeding jQ in your own webpage

You can embed jQ in your own webpage. It's really easy. It is enough to place the following HTML code in your page 

<div class="_jq"></div>

followed by 

<script src="http://qugate.org/jQ/jQ.js"></script>

somwhere at the end of your page. All together should look like that: 

<body>

...

<div class="_jq"></div>

...

<script src="http://qugate.org/jQ/jQ.js"></script>
</body>

You can embed as many <div class="_jq"></div> as you need, but you must place <script src="http://qugate.org/jQ/jQ.js"> below all of them in HTML code.

If you want to place a qunatum circiut in your jQ, you just do the following 

<div class="_jq">
<!--
[ H(0), H(1), H(2), U([0,1,2],[3,4,5], function(x) {return Math.pow(7,x)%8; }, 'f'), H(2), C(1,R(1,2)), C(0, R(2,2)), H(1), C(0, R(1,1)), H(0) ]
-->
</div>
