How to build a quantum circuit with Cirq 1.0

The first step in programming a quantum computer is creating a quantum circuit. In this video, we explore how to build quantum circuits with Cirq 1.0.

Resources:

Chapters:
0:00 – Intro & quickly installing Cirq 1.0 in Colab
2:12 – Creating qubits
7:51 – Adding quantum gates on qubits to circuits, moments
14:15 – Adding measurements, testing quantum circuits quickly

Thanks a ton for the tutorials :) I have a couple of comments:

1. At 15:51 you have written the code for the three CNOT gates in the opposite order of what's in the circuit's screenshot from the book. Well, I checked and it doesn't make any difference to the end result (pattern 110011) but just to make it clear I brought it up. Please correct me if I am wrong.

2. For all the other gates it starts with an uppercase, as in cirq.X cirq.Z cirq.H cirq.Moment cirq.Simuator etc. but why is it for measurement in lowercase i.e. cirq.measure ... Perhaps a silly question, but it would have been more convenient if it was rather just cirq.Measure

Will I be able to test the latest discoveries on Quantum Internet like Quantum Router Architecture?

From 19:58 the code was not in sync with the narrating person, ending up not simulating the circuit and showing results.

Great tutorials!
Can you post the link about the algorithm mentioned on the video for this particular quantum circuit.
Thanks !

Very interesting for learning for 16 year olds like me😅

Hi,
I think the CNOT gates that you mentioned in the tutorial doesn't go from 0 to 5, 1 to 5, and 4 to 5. Instead they go from 4 to 5, 1 to 5, and 0 to 5.

I didn't understand the name of the author of the book Quantum Computer Science: An Introduction.
