World Quantum Day (April 14, 2023) Collaboration with the QED-C

According to the World Quantum Day Org, World Quantum Day is celebrated on April 14, a reference to 4.14, the rounded first digits of Planck’s constant.

This year, Photodigm celebrated World Quantum Day by partnering with the QED-C, Quantum Economic Development Consortium, to create a video miniseries raising awareness of the impact of quantum science and technology.

The QED-C asked us to focus on “How will quantum impact… biomedical diagnostics?” and we answered in this 1-minute video!

👋 Our team is proud to supply #quantumtechnology! We design, test, and manufacture single-frequency #DBR laser diodes 730–1090 nm which are essential to #biomedical sensing applications. Quantum biomedical diagnostic technology enables better patient care with non-invasive less stressful procedures. Doctors can build confident treatment plans by receiving real-time accurate insights into the 🧠 human brain, 💚 heart, and more! #WorldQuantumDay

You can see the QED-C’s full video miniseries on this YouTube playlist.
