This past summer (Summer 2014), Elena Polozova and Bijan Mazaheri developed a nice quantum circuit simulator in Mathematica.
This simulator allows one to enter the circuit in text input (as a list of characters), with each row a qubit and each column a quantum logic gate (including Hadamard, phase gates, and CNOT). A quantum circuit is produced along with the matrix representation of each step in the circuit. We have simulated the Quantum Fourier Transform and Grover Search; Shor’s Algorithm is to come!

I will be speaking about my work on the quantum mechanics of superconducting circuits—all are welcome! [Update: Slides can be found here]
Entanglement: Schrödinger’s Quirky Quantum Conundrum
In quantum mechanics, one can have complete knowledge of the whole but complete ignorance of the parts. This phenomenon, famously discovered by Einstein, Podolsky, and Rosen, was subsequently christened entanglement by Schrödinger. This first talk will introduce this quirky phenomenon and its application to quantum communication, cryptography, computing, and experimental metaphysics.

Entanglement in Superconducting Quantum Circuits
Superconducting circuits can be used to control electrical signals at the level of single quanta. Such devices have shown energy level quantization, superposition of states, and may one day serve as quantum bits (qubits) in a large-scale quantum computer. This second talk will describe my research in the design and study of multi-qubit entanglement in superconducting circuits.
