We calculate spin correlation functions using IBM quantum processors, accessed online. We demonstrate the rotational invariance of the singlet state, interesting properties of the triplet states, and surprising features of a state of three entangled qubits. This exercise is ideal for remote learning and generates data with real quantum mechanical systems that are impractical to investigate in the local laboratory. Students learn a wide variety of skills, including calculation of multipartite…

Five Experimental Tests on the 5-Qubit IBM Quantum Computer

The 5-qubit quantum computer prototypes that IBM has given open access to on the cloud allow the implementation of real experiments on a quantum processor. We present the results obtained in five

Undergraduate computational physics projects on quantum computing

Computational projects on quantum computing suitable for students in a junior-level quantum mechanics course are described. In these projects students write their own programs to simulate quantum

Simulating quantum many-body dynamics on a current digital quantum computer

Universal quantum computers are potentially an ideal setting for simulating many-body quantum dynamics that is out of reach for classical digital computers. We use state-of-the-art IBM quantum

TLDR
The experimental optimization of Hamiltonian problems with up to six qubits and more than one hundred Pauli terms is demonstrated, determining the ground-state energy for molecules of increasing size, up to BeH2.

TLDR
Efficient randomized algorithms are given for factoring integers and finding discrete logarithms, two problems that are generally thought to be hard on classical computers and that have been used as the basis of several proposed cryptosystems.

Quantum Transpiler Optimization: On the Development, Implementation, and Use of a Quantum Research Testbed

TLDR
A testbed is proposed to provide abstractions to create and test transpiler routines and initial results are provided that suggest more effective algorithms for qubit mapping and state movement.

On the CNOT-cost of TOFFOLI gates

TLDR
It is proved that the n-qubit analogue of the TOFFOLI requires at least 2n CNOT gates, and a complete classification of three-qu bit diagonaloperators by their CNOT-cost, which holds even if ancilla qubits are available.

On the Spin Projection Operator and the Probabilistic Meaning of the Bipartite Correlation Function

Spin is a fundamental and distinctive property of the electron, having far-reaching implications. Yet its purely formal treatment often blurs the physical content and meaning of the spin operator and
