This is an extract from a BluGlass paper 26April this year:
Unlocking the laser opportunity in quantumQuantum information science is rapidly advancing, driving urgent need for compact, single-wavelength (single-frequency) laser light sources. Advancements in quantum computing and quantum applications are being underpinned by stimulated light interaction with unique materials, down to the atomic scale, requiring specific wavelengths to target individual atomic interactions.The physics of nature dictates the unique wavelengths required to interact with specific atoms, crystals, and the environment. Many of these needed wavelengths are in the near ultra-violet (UVA) and visible spectrums. Due to their unique lasing properties, gallium nitride (GaN) lasers are ideally positioned to address these nature-dictatedUVA and visible wavelengths.Emerging quantum markets present an enormous opportunity for visible laser diode manufacturers, such asBluGlass, as many of the enabling atomic transitions occur at visible wavelengths and are being increasingly sought after by customers in highly promising applications, including advanced robotics and bio-medical devices.Brain-driven prosthetic automation and atomic clocks for quantum navigation used in military and commercial applications are good examples of this next-generation tech.In its 2021 quantum report McKinsey & Company reported, “Quantum computing, one of the most revolutionarytechnologies of our time, is still a decade away from widespread commercial application. However, less wellknown, but of critical industrial and scientific importance, are two related technologies that are set to becomeavailable much earlier: quantum sensing (QS) and quantum communication (QComm).”Quantum sensing technologies are advancing more quickly and are positioned to become available sooner thanfull-scale quantum computers. These include ultra-precise sensors for advanced defence and aviation applications for measuring gravity, magnetic fields, and time. Further, these technologies will enable atomic clocks, which serve as the backbone for quantum navigation and synchronisation.Finally, quantum communication (QComm) is an emerging technology promising unbreakable encryption and secure communication via quantum key distribution (QKD).
