Statement of Work

For

Magneto-Optical Traps

I. Background:

There are many challenges facing the implementation of quantum information systems that are affordable, portable, and robust. While there are numerous candidates for the stationary qubits found in quantum computers, the most likely candidate for transmitted or “flying” qubits is the photon. Therefore, the ability to store photos reliably for extended periods of time is necessary for the processing of photonic qubits and the establishment of entanglement between distant nodes in a quantum network. However, the process of storage will by its nature distort the retrieved photonic states and thus distort the information encoded by the photons.

The Coherent Atomic Transfer (CAT) function is a framework developed for storing light pulses in a -type atomic system using the phenomenon of electromagnetically induced transparency (EIT). The specific goal of this proposal is to build an experimental setup for the storage of light using EIT, which includes setting up the experiment, characterizing the alkali cells spectroscopically, and inducing EIT using a targeted set of atomic energy transitions and appropriately tuned lasers. The magneto optical traps will be used in conjunction with the laboratory section of OENG 655 for the purposes of exploration of sensing quantum coherence. The higher-vacuum magneto optical traps will likely be integrated into the future AFIT-OSU quantum network as a storage node for qubits over fiber. All four of these devices will be used in the research of EIT storage for quantum light and quantum sensing with Rydberg atoms.

II. Minimum Technical Requirements:

The following specification lists the minimum requirements for magneto-optical traps (MOTs). Objective requirements are also highlighted when available.

The magneto-optical trap will be used to generate cold groups of alkali atoms. Four components are necessary for meeting mission requirements: two fully built compact magneto-optical traps suitable for laboratory courses (one using cesium atoms and one using rubidium atoms) and two fully built ultra-high vacuum systems for student and faculty research efforts (one using cesium atoms and one using rubidium atoms).

1. The compact MOTs shall meet the following requirements for both the cesium and rubidium variants:

1.1. Each compact MOT will fit in a 12x12x12 inch space

1.3. Generate a magnetic field gradient of >=13 Gauss/(A-cm)

1.4. Use a cell with an anti-reflection coating with a minimum range of 700-1000 nm with an optical flatness of <=𝜆𝜆/2 per cm

1.5. Anti-Helmoltz magnetic field coils with an inductance of >= 5 mHenri capable of producing a magnetic quadrupole field, with driving electronics instruments.

1.6. An ion pump with power supply with an atomic flux rate of >=0.4 L/s

1.7. A passive getter pump with power supply

1.8. An alkali metal dispenser compatible with rubidium and cesium with a failsafe system to prevent over-dispensation of alkali atoms, with power supply.

1.9. Validation of dispenser performance using a built-in fluorescence measuring detector.

1.10. An integrated user interface to monitor and control magnetic coils, dispenser, and ion pump

1.11. A pre-aligned optics train beam delivery system to interface with the atomic alkali

1.12. Software and drivers must be included

1.13. A power supply with an input AC voltage between 100-240 V and an input frequency of 50-60 Hz, and an output DC voltage between 11.8-12.6 V.

2. The ultra-high vacuum MOTs (UHV-MOTS) shall meet the following requirements for both the cesium and rubidium variants:

2.1. The (UHV-MOTS) must fit in a 12x12x12 inch space

2.2. An atomic delivery system with an injection rate of >=108 atoms/s

2.3. Generate a vacuum of <= 1x 10-9 Torr pressure.

2.4. Generate an atomic ensemble of >=108 atoms

2.11. Software and drivers included.

3. Delivery:

SHIP TO:

Air Force Institute of Technology (AFIT/ENP) ATTN: Greg Smith 2950 Hobson Way Wright-Patterson AFB, OH 45433-7765

4. Lead Time:

The contractor shall deliver ordered systems 5 months after contract approval.

5. Warranty: Must provide 1 year warranty from date of acceptance.

III. Delivery Procedures – Commercial Vehicles:

a. The company shall ship the system to the Air Force Institute of Technology at

WPAFB, OH. All shipping costs to include insurance will be included in the contractor’s proposal. Great care using standard, approved packaging methods shall be taken.

b. All vehicles larger than a large pick-up truck are required to be inspected by the Wright- Patterson Air Force Base Commercial Vehicle Delivery Gate (CVDG) prior to entering the installation. Vehicles to be inspected include, but are not limited to, the following:

1. Step van/panel truck

2. Tractor/trailer, box and flatbed containing cargo

3. Tanker trucks

4. Box trucks

5. Tour buses

6. Garbage/recycled waste trucks

7. Concrete trucks/mixers, dump trucks

8. Cranes, recreational vehicles, petroleum tanker

This inspection will be conducted at Gate 26A located off State Route 235.

c. The following are exemptions to vehicles utilizing the CVDG:

1. If the vehicle has the product inside (concrete and asphalt trucks) and timely delivery is necessary due to product deterioration it does not need to enter the CVDG. To bypass the CVDG, the contractor shall submit a list containing drivers’ names, social security numbers and the state in which the driver's license is held for those drivers who will be entering the base. This shall be accomplished 24 hours prior to requested entry time. If entry is requested on Monday, this list must be submitted by Friday at 1630 hours. All lists shall be submitted to the 88th ABW/CE Directorate contract inspector. The only gates that may be used under this exemption shall be 15A, 26A, 38A, and gate 1B. If the driver's name is not on the list, he/she will not be allowed access to the installation through these gates and the base will not assume liability for denied access.

2. If a delivery vehicle must exit, and then re-enter the base to complete its route, the vehicle shall be resealed upon exiting the base. After passing through the commercial vehicle delivery gate, trucks shall be resealed at Gates 15A, 38A and 22B. The resealing of the trucks will allow them to continue to any other area of the installation (Areas A, B, or Kittyhawk) without reprocessing through the CVDG. To receive resealing assistance, the drivers shall physically stop at one of the three authorized gates and request the installation entry controller to reseal their truck and provide the next location of their delivery. The controller will reseal the truck and give the delivery driver a pre-clearance form. The driver shall present the pre-clearance form to the entry controller at the next point of installation entry. This reentry can be through any base gate.

d. Vehicles may be subject to an inspection at any of installation entry control points during a directed random antiterrorism measure (RAM.) Any commercial vehicle, regardless of size, can be directed to the CVDG at the discretion of the installation entry controller.

IV. This will be a firm fixed price contract, and payment will be made using Wide Area

Work-Flow (WWAF).
