<p>Components of the Milkymist system-on-chip soon found many other uses, such as <a href="jpl_letter.jpg">software-defined radio</a> on board the International Space Station. The community grew and activities diversified, with the development of a <a href="http://www.ohwr.org/projects/tdc-core/wiki">TDC core</a> for CERN (using a variant of the Milkymist SoC for integration), the <a href="gateware.html">Migen</a> logic design system and its application to the <a href="http://rhinoplatform.org/">Rhino</a> software-defined radio platform, and the <a href="mixxeo.html">Mixxeo</a> digital video mixer. In 2013, Milkymist was renamed to M-Labs to mark the more varied activities. It is formally incorporated as M-Labs Limited.</p>
<p>The company's current main project is <a href="artiq/index.html">ARTIQ</a>, a next-generation open source control system for quantum information experiments.</p>

<p>ARTIQ (Advanced Real-Time Infrastructure for Quantum physics) is a next-generation control system for quantum information experiments. It is being developed in partnership with the <a href="http://www.nist.gov/pml/div688/grp10/index.cfm">Ion Storage Group</a> at NIST, and its applicability reaches beyond ion trapping.</p>
<p>Modern research on quantum information systems poses particular challenges to the control system:
<ul>
<li>dozens of signals need to be received and generated with extremely precise timing, in particular to ensure phase coherence</li>
<li>quantum error correction schemes require very low reaction latency in response to a measurement</li>
<li>real-world implementations of quantum gates, and a fortiori quantum algorithms, involve structurally complex protocols</li>
<li>ever-improving experimental techniques drive the need for a flexible and programmable system</li>
<li>the diversity of equipment, device drivers and data analysis software involved in a single experiment results in a distributed and multi-platform environment</li>
</ul>
</p>
<p><center><img src="lab_hardware.png"></center></p>
<h2>Enter ARTIQ</h2>
<p>ARTIQ features a high-level programming language, based on Python, that helps describing complex experiments. It is compiled and executed on dedicated FPGA hardware with nanosecond timing resolution and sub-microsecond latency.</p>
<p>The time-critical code (a <i>kernel</i>) running on the FPGA (the <i>core device</i>) is easily interfaced with Python code on the computer using a remote procedure call (RPC) mechanism.</p>
<p>The FPGA design is highly portable so that it can adapt to different laboratory setups and resist hardware obsolescence.</p>
<p>ARTIQ drivers for non-realtime devices can be run on remote machines with different operating systems.</p>
<p>The project also includes a graphical user interface, an experiment scheduling system, and databases for experiments, devices, parameters and results.</p>
<p>Technologies employed include <a href="http://python.org">Python</a>, <a href="../gateware.html">Migen</a>, <a href="../gateware.html">MiSoC</a>/<a href="https://github.com/openrisc/mor1kx">mor1kx</a>, <a href="http://llvm.org">LLVM</a> and <a href="https://github.com/numba/llvmlite">llvmlite</a>.</p>
<p><center><img src="comp.png"></center></p>
<h2>A taste of the programming language</h2>
<h4>Timing language basics</h4>
<pre>
trigger.sync() # wait for trigger input
start = now() # capture trigger time
for i in range(3):
delay(5*us)
dds.pulse(900*MHz, 7*us) # first pulse 5 µs after trigger
at(start + 1*ms) # re-reference time-line
dds.pulse(200*MHz, 11*us) # exactly 1 ms after trigger
</pre>
<p>
<ul>
<li>now(), at(), delay() describe time-line of an experiment</li>
<li>Exact time is kept in an internal variable</li>
<li>That variable only loosely tracks the execution time of CPU instructions</li>
<li>The value of that variable is exchanged with the real-time input/output (RTIO) core that does precise timing</li>
</ul>
</p>
<h4>Parallelism</h4>
<pre>
with sequential:
with parallel:
a.pulse(100*MHz, 10*us)
b.pulse(200*MHz, 20*us)
with parallel:
c.pulse(300*MHz, 30*us)
d.pulse(400*MHz, 20*us)
</pre>
<ul>
<li>Experiments are inherently parallel: simultaneous laser pulses, parallel cooling of ions in different trap zones</li>
<li>parallel and sequential contexts with arbitrary nesting</li>
<li>a and b pulses both start at the same time</li>
<li>c and d pulses both start when a and b are both done (after 20 µs)</li>
<li>Currently implemented by inlining, loop-unrolling, and interleaving (i.e. static scheduling at compile time)</li>
</ul>
<h4>Organize experiment components and reuse code</h4>
<pre>
class Experiment(AutoDB):
def build(self):
self.ion1 = Ion(...)
self.ion2 = Ion(...)
self.transporter = Transporter(...)
@kernel
def run(self):
with parallel:
self.ion1.cool(duration=10*us)
self.ion2.cool(frequency=...)
self.transporter.move(speed=...)
delay(100*ms)
self.ion1.detect(duration=...)
</pre>
<h2>Is ARTIQ right for my lab?</h2>
<div style="float: right;"><img src="logo_small.png"></div>
<p>If you don't mind <a href="manual/installing.html">getting your hands dirty</a> (i.e. compiling software and FPGA bitstreams), it's easy to find out by yourself! The core device is based on the resource-efficient MiSoC system-on-chip design, and you can use a limited version of ARTIQ with the small and low-cost <a href="http://papilio.cc/">Papilio Pro</a> board. Feel free to send feedback to the mailing list!</p>
<p>Note that ARTIQ is still in development and we expect to deploy a fully functional release (that will include a GUI) at NIST by June 2015. We are also working on making the installation procedure easier.</p>
