Laser Cinema, Coming Someday to a Theater Near You--Maybe

Engineers in China have built a laser digital cinema projector

3 min read

14 October 2008—The first laser TV is set to go on sale soon in North America, but engineers from the Academy of Opto-Electronics at the Chinese Academy of Sciences and Phoebus Vision Opto-Electronics, in Beijing, say they’ve already brought the eye-popping color of laser-generated images to the big screen with a digital cinema projector that uses lasers as the light source. The team combined several lasers with the MEMS technology used in digital projectors today. They describe the device in September’s Journal of Display Technology.

The technology ”will be the next generation of cinema display,” says Yong Bi, a professor at the Chinese Academy of Sciences and chief technology officer at Phoebus, which is commercializing the projector. However, others in the industry question whether laser cinema will be ready in time and inexpensive enough to catch much of the market.

An IBM Quantum Computer Will Soon Pass the 1,000-Qubit Mark

The Condor processor is just one quantum-computing advance slated for 2023

IBM’s Condor, the world’s first universal quantum computer with more than 1,000 qubits, is set to debut in 2023. The year is also expected to see IBM launch Heron, the first of a new flock of modular quantum processors that the company says may help it produce quantum computers with more than 4,000 qubits by 2025.

This article is part of our special report Top Tech 2023.

While quantum computers can, in theory, quickly find answers to problems that classical computers would take eons to solve, today’s quantum hardware is still short on qubits, limiting its usefulness. Entanglement and other quantum states necessary for quantum computation are infamously fragile, being susceptible to heat and other disturbances, which makes scaling up the number of qubits a huge technical challenge.
