Sinara is an open-source (CERN OHL v1.2) hardware ecosystem designed by physicists for use in quantum science laboratories largely focused on work with trapped atomic ion qubits. Sinara is designed to work closely with the ARTIQ control software. While Sinara and ARTIQ were founded by a particular niche in the experimental physics community, users and contributors from all disciplines are invited to use and contribute to the project.


Control electronics used in many atomic physics laboratories suffers from a number of problems. Control solutions developed in-house by physicists often optimize for lab-specific needs and the publish-or-perish reality of many PIs circumstances. The result is solutions that compromise on architectural design, reproducibility, testing and documentation which translates into systems that are fragile, difficulty to reproduce in other labs and hard to maintain. It also duplicates similar infrastructural work undertaken in other laboratories. Further, the performance and feature set of commercial off the shelf hardware-software solutions is poorly matched to many labs needs (e.g. RF pulse shaping, branching latency).

To alleviate those problems, Sinara aims to be:

  • fully transparent design workflow
  • open source hardware, firmware and unit tests
  • simple to use and "turn-key" (we're not quite "turn-key" yet)
  • reproducible
  • flexible and modular
  • well tested at the hardware level
  • well supported by the ARTIQ control software

Sinara is currently developed by a collaboration including M-Labs, QUARTIQ, Warsaw University of Technology (WUT), US Army Research Laboratory (ARL), the University of Oxford, the University of Maryland, the University of Oregon, and NIST. The majority of the hardware was designed by WUT. The work was funded by ARL, Duke University, the University of Oxford, the University of Oregon, and the University of Freiburg.

Currently, much of this hardware is well tested, commercially available and deployed for routine use in many AMO labs. Information about the status of the various hardware projects making up Sinara can be found here. Options for purchasing Sinara hardware can be found here.

Overview

Following the ARTIQ model, a minimal laboratory setup consists of a core device (master) -- typically either a Metlino or Kasli -- controlling multiple slave devices in real time using the ARTIQ distributed real-time IO (DRTIO) protocol. DRTIO provides both gigabit communication links and time distribution over copper cable or optical fiber. It synchronizes all device clocks, ensuring they have deterministic phase relationships, and enables nanosecond timing resolution for input and output events across all devices in the experiment. More detailed information about communication between devices and time distribution inside Sinara can be found here.

Sinara uses two main form factors for hardware requiring real-time control: microTCA (uTCA) and Eurocard Extension Modules (EEM). Non real-time hardware is typically connected to the host PC using ethernet.

MicroTCA (uTCA) is Sinara's preferred form factor for high performance hardware with high-speed data converters requiring deterministic phase control, such as the Sayma Smart Arbitrary Waveform Generator (SAWG). Information about uTCA hardware, including a list of parts needed to build a Sinara uTCA crate can be found here.

EEMs provide a lower cost, simpler platform than uTCA for hardware that requires real-time control, but not bandwidth or complexity of uTCA hardware.

Extension modules connect to a carrier, such as Kasli or the VHDCI carrier, which provides power and DRTIO. They are designed to be mounted either in stand-alone enclosures, or in a rack with a carrier, and connect to the carrier via ribbon cable. More details about the extension module standard can be found here.

uTCA hardware interfaces with the extension modules either directly, using a VHDCI carrier, or indirectly, using a Kasli DRTIO slave.

MicroTCA hardware

An overview of uTCA in Sinara can be found here, for more detailed information on specific topics, see the links below. The uTCA hardware is still in beta and not yet fullly supported by ARTIQ. See this page for status.

Kasli and extensions

  • Information about the Eurocard Extension Module (EEM) standard can be found here.
  • Not all PCBs in this section are fully debugged and supported by ARTIQ. See this page for status.
  • Code for provisioning of Kasli hardware is here.
  • Code for testing of Kasli-based crates is here.

Project structure and development

Development discussions take place on two forums: the GitHub issue trackers for well-defined actionable items; and the web forum for more vague questions, general brainstorming, new hardware proposals, discussions about funding, and so forth.

Two main CAD tool used for PCB design within Sinara is Altium Designer. Altium Designer is preferred for more complex designs, such as the uTCA and EEM hardware. Kicad is also used for simple designs, like adapters, in particular, those intended to be modifiable by the users (physicists).
