BQIT 2019
We had a great time at BQIT this year here in Bristol. Here’s a short video with some highlights of our booth and what we’ve been up to.

See you at BQIT 2019!
We’re happy to announce that we are a Bronze sponsor at this year’s Bristol Quantum Information Technologies Workshop BQIT, April 1-3. This is really exciting for us because it’s the first conference we have sponsored, and it’s with our favourite people, QETlabs, here in Bristol.
We’ll have a booth set up with some demos throughout the conference, and both of us (Liz and Josh) will be there, so come and say hi. Come check out our existing products, and an exciting new product to launch too! And don’t forget to pick up some swag-nets while you’re at it.
How to connect to your chip
This question comes up often. In this post, we outline some of the different approaches and discuss the interposers which we stock for various scenarios. If none of our existing interposers meet your needs, please contact us with your special product request.
We stock a variety of interposer PCBs. These take in the bulky 60 or 68-way cables from our line of docks and break them out into smaller connectors for wiring your devices. Most interposers present two or more identical output connectors. Some contain integrated patch panels, to allow manual re-wiring of the device. Others are directly wired, and rely on reconfiguration in software.
Our new driver, the Q8iv, is coming
We’ve started testing for our first run of the Q8iv, coming soon. Contact us for details.

Which driver is right for you?
Choosing a driver for your photonic device can be a difficult task. Though we hope that our drivers are the best fit, there are several parameters to keep in mind.
- How much current does each input of my device require?
- How much voltage is required to achieve this current?
- What is the resistance of my on-chip heaters?
- What precision do I need?
- Does my device care about the direction of current flow?
- How many inputs does my device have that need to be driven?
