SUMMARY:Protocol for robust quantum networks\, Preliminary Exam\, Omar
  Khaled Nagib Abdelhakim Mohamed\, Physics PhD Graduate Student
DESCRIPTION:Quantum networks consist of quantum nodes (e.g.\, atomic q
 ubits) connected by remote entanglement. For scalable quantum networks
 \, it is essential to engineer interactions between remote atomic qubi
 ts. This is typically achieved through two-qubit gates between atomic 
 qubits in cavities and flying photons. Previous schemes have been sens
 itive to experimental imperfections\, with fidelities limited to the r
 ange of 75–80%. I propose an atom-photon CZ gate that utilizes doubl
 y degenerate ground and excited state energy levels to mediate the ato
 m-light interaction. The setup consists of a cavity and a Mach-Zehnder
  interferometer. The gate operates by converting error-inducing photon
 s into losses\, making the scheme less sensitive to errors compared to
  previous schemes.<br>

\nI will also discuss my research progre
 ss on two additional projects. The first project proposes the use of G
 rover's algorithm in a cavity to efficiently prepare entangled states 
 of many qubits. The second project is a mathematical and numerical met
 hod that enables fast simulation of open quantum systems through the u
 se of generalized inverses.
