DIGIBEAM CORPORATION — Department of Defense SBIR Phase II: AF203-DCSO3

Description

Since the development of efficient factoring of large numbers, quantum information processing has gained widespread interest, driving the need to realize a quantum computer. The use of tapped ions has proved over the years to be one of the most successful way of deterministically creating entangled states for manipulating, characterizing and using these states for measurement. Desirable for these systems is the ability to have a collection of quantum systems that can individually manipulate their entangled states, and their coherences maintained for long durations while suppressing the effects of unwanted couplings to the environment.  Among the path to develop these systems is the Pauli trap containment with a time sequenced laser cooling applied to the trapped ion and independently measuring the decay from hyperfine doublets defining states |0>, and |1>. Digibeam is presenting a unique slow wave structure with ultra-fine granularity control of electric fields, coupled with high optical access and compact in size called the Compact Room Temperature Ion Quantum Trap or (CRQT). The system features high density self-aligned laser cool and sensing, capable of independently adjusting trap channels for long linear ion chains beyond 20 trap, cool and sense channels per single ion chain.
