Lumentum Delivers Revised Acquisition Bid for Coherent Worth $6.9B SAN JOSE, Calif., March 17, 2021 — Lumentum revised its proposal to acquire Coherent, delivering a cash and stock purchase offer valued at $6.9 billion. The Lumentum offer is in response to the latest Coherent acquisition proposal from II-VI, which was announced last week. Coherent, following its receipt of that II-VI proposal, said its board had determined II-VI’s latest bid to be superior to terms of a merger agreement it had with Lumentum on March 10. That proposal, II-VI said, carried an enterprise value of $6.8
Optical Fiber Brings Universal Quantum Computing Closer GAITHERSBURG, Md., March 25, 2021 — Physicists at the National Institute of Standards and Technology (NIST) measured and controlled a superconducting qubit using optical fiber, rather than metal electrical wires. The work moves toward a universal quantum computer capable of solving...
