Entanglement lifetime extended orders of magnitude using coupled cavities




(Phys.org)—Entangled qubits form the basic building blocks of quantum computers and other quantum technologies, but when qubits lose their entanglement, they lose their quantum advantage over classical bits. Unfortunately, entanglement decays very quickly due to unavoidable interactions with the surrounding environment, so preserving entanglement for long enough to use it has been a key challenge for realizing quantum technologies.
