Quantum logic gates are basic blocks to construct quantum computing and quantum information processing systems. Quantum logic gates based on coupled-resonator optical waveguide (CROW) are analyzed with the advantage of integration with other devices. Photonic crystal CROW (PhC CROW) structure with different dimension and background medium exhibits electromagnetically induced transparency (EIT), which is used as single quantum bit (qubit) phase gate. Quantum Hadamard gate can also be realized by coupling element. Two qubit conditional quantum phase gate is achieved by concatenating two Hadamard gates and a phase gate doped with dopant. The simplicity and dynamic tunability of the device could be a useful solution for quantum information processing.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
