 The way that information is processed in a superconducting quantum computer is via microwaves, much like the microwave oven that you have at home, only that we use the microwaves at a much smaller scale. The problem with the information being encoded in microwaves is that we can't transfer them via room temperature because they are prone to thermal interference. So what we have to do in order to connect to cryostats which contain quantum computers is that we have to convert the information from the microwave domain to a more robust format. And how we do that is we convert it into optical photons. And much like the internet access that you have at home, we can then use fiber optic cables to transmit the information to the other corner computer where it is then converted back into microwave photons. When we talk about quantum links in the context of superconducting quantum computers, what we mean is some device that can connect different dilution refrigerators that contain superconducting qubits by a coherent means. And that means that we have to convert the information in a superconducting qubit from the microwave domain to the optical domain where the qubit is more robust and where we can easily transport it through fiber optic cables without having to be afraid to lose the quantum information on the way. And this is important because it enables us to create large quantum networks between different quantum computers which means that we can scale up the power of a single quantum computer by distributing the computing over several nodes in a network. Here in Europe we are working on a Horizon 2020 project which is called Optomechanical Technologies, which I am a part of. And in this project I am trying to implement a device, a quantum link, via something called Optomechanics. And this is actually a very exciting method to convert quantum information from the microwave to the optical domain because what we use is a tuning fork in the middle. So we can basically transmit or convert the information encoded in a microwave qubit into a mechanical phonon in the quantum excitation in this mechanical resonator and then this mechanical excitation is coupled to a light field. And we can do this very efficiently and this is actually one of the few ways that you can basically be efficient enough to couple light directly to the microwave domain. Since we are working at the moment on the very basic level, so we are trying to implement the first devices and we are trying to integrate that with our platform for superconducting qubits, the time frame that we are looking at is maybe three to five years until we actually can demonstrate the first working quantum links. So what I am working on at the moment is to implement the first devices where we can actually use microwaves to directly couple to a light field with low-loss using Optomechanics.
