Stabilized laser components could shrink quantum computers from room- to chip-scale Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California Santa Barbara have demonstrated key laser and ion trap components necessary to help drastically shrink the size of quantum computers, an achievement aligned with the shrinking of integrated microprocessors in the 1970s, 80s and 90s that allowed computers to move from room-sized behemoths to today's ultrathin smartphones.

Stabilized laser components on photonic chips demonstrate a path toward shrinking quantum computers and optical clocks from room-sized systems to chip-scale devices, advancing scalability and portability. doi.org/hbvc59

I'm posting my Intro to Quantum Computing Course on Github this year.

github.com/UMassIonTrap...

13 interactive Colabs
16 recorded lecture (so far)
70 pages of 'Goodnotes'

Focus is visual and interactive learning of how qubits work (eg. RWA below)

Hope it's helpful!
I'll post updates as we go!

Single-qubit gates with errors at the $10^{-7}$ level We report the achievement of single-qubit gates with sub-part-per-million error rates, in a trapped-ion $^{43}$Ca$^{+}$ hyperfine clock qubit. We explore the speed/fidelity trade-off for gate times $4...

PSA reminder to stop talking about Majorana’s and start talking about how real qubit’s are surpassing the ppm error threshold… arxiv.org/abs/2412.04421

Reviewer 4!

LOL!

I lol’d! Thanks! 🤣

We hope that PyOpticL can become a hub for open-source optical hardware design for trapped ions and AMO experiments. Please let me know if you're interested in using it!

PyOpticL (github.com/UMassIonTrap...) is a dynamic optical layout tool for optical system engineering (including laser sources), which we use for trapped ion qubit operations such as laser cooling, detection and single qubit gates. The repo includes CAD files for double pass baseplates and more.

Qubit operations using a modular optical system engineered with PyOpticL: a code-to-CAD optical layout tool Complex optical design is hindered by conventional piecewise setup, which prevents modularization and therefore abstraction of subsystems at the circuit level. This limits multiple fields that require...
