    "abstract": "Quantum computers are expected to be able to solve mathematical problems that\ncannot be solved using conventional computers. Many of these problems are of\npractical importance, especially in the areas of cryptography and secure\ncommunications. APL is developing an optical approach to quantum computing in\nwhich the bits, or \"qubits\", are represented by single photons. Our approach\nallows the use of ordinary (linear) optical elements that are available for the\nmost part as off-the-shelf components. Recent experimental demonstrations of a\nvariety of logic gates for single photons, a prototype memory device, and other\ndevices will be described.",
