Bell circuit Updated 2025-07-16
A quantum circuit which when fed with input produces the Bell state.

The fundamental intuition for this circuit is as follows.
First the Hadamard gate makes the first qubit be in a 50/50 state.
Then, the CNOT gate gets controlled by that 50/50 value, and the controlled qubit also gets 50/50 chance as a result.
However, both qubits are now entangled: the result of the second qubit depends on the result of the first one. Because:
OpenQASM Updated 2025-07-16
On Qiskit qiskit==0.44.1:
qc.qasm()
E.g. with our qiskit/hello.py, we obtain the Bell state circuit:
OPENQASM 2.0;
include "qelib1.inc";
qreg q[2];
creg c[2];
h q[0];
cx q[0],q[1];
measure q[0] -> c[0];
measure q[1] -> c[1];
Quantum circuit description language Updated 2025-07-16
These are a bit like the Verilog of quantum computing.
One would hope that they are not Turing complete, this way they may serve as a way to pass on data in such a way that the receiver knows they will only be doing so much computation in advance to unpack the circuit. So it would be like JSON is for JavaScript.
Quantum compiler benchmark Updated 2025-07-16
These appear to be benchmarks that don't involve running anything concretely, just compiling and likely then counting gates:
R (programming language) Updated 2025-07-16
Ubuntu 23.04 install:
sudo apt install rbase
Hello world:
R -e 'print("hello world")'
Install a package, e.g. Bookdown:
sudo R -e 'install.packages("bookdown")'
Animal-in-the-loop Updated 2025-07-16
Ciro Santilli invented this term, it refers to mechanisms in which you put an animal in a virtual world that the animal can control, and where you can measure the animal's outputs.
Classification of finite rings Updated 2025-07-16
accounts for them all, which we know how to do due to the classification of finite fields.
So we see that the classification is quite simple, much like the classification of finite fields, and in strict opposition to the classification of finite simple groups (not to mention the 2023 lack of classification for non simple finite groups!)

There are unlisted articles, also show them or only show them.
