QBoard is a state-of-the-art multipurpose cryogenic quantum chip holder system. It offers excellent thermalization down to millikelvin covers and a broad operating spectrum from DC up to 8 GHz. With 48 DC/low-frequency channels and 16 high-frequency channels (GHz), QBoard supports control and readout of up to eight spin qubits.
QBoard consists of a motherboard, multiple daughterboard sample holder options, an interposer, a mounting bracket, and all necessary cables for connecting the QBoard to the cold finger of a typical dilution refrigerator, or to the inside of cryostat’s measurement insert.
The quantum chip is mounted and wire bonded to a daughterboard (6.3×6.8 mm ² and 10.5×10.5mm² sample space options). It serves as a chip carrier, offering a high degree of flexibility. The daughterboard has a 0.5 mm deep gold plated cavity into which the sample chip can be glued.
The high-frequency daughterboard (6.3×10.5 mm² sample space) extends the frequency range of the system to at least 12 GHz with four on-board mini-SMP connectors. This is useful for applications such as readout of superconducting resonators, sub-nanosecond gate-voltage pulses, and high-bandwidth frequency sweeps.
A grounding plate grounds and protects samples from ESD while mounting, wire bonding, and transferring these in the QBoard daughterboards. The grounding plate is used with the QBoard Interposer to ground all lines from the daughterboard while mounting and wire bonding chips. A short cable is provided to connect securely to the ground, both in the wire bonder and while the daughterboard is transferred to the QBoard motherboard.
“QCage integrates seamlessly into our workflow of preparing and loading QPUs and supports higher throughput in our lab. Our research directly benefits from QCage's innovative design and engineering.”
“QM's chip packaging solutions are exquisite pieces of engineering that have enhanced our resonator Q-factors to as much as 200 million. It is clearly a very highly engineered product that I am sure will be widely adopted in our field.”
“Developing a functional qubit control electronic system absorbs a PhD-student full time at least for two years. QM’S Quantum Orchestration Platform allowed us set up experiments for full qubit characterization in 2-3 days with an undergraduate summer school student.”
“The quantum orchestration platform (QOP) platform completely changed the way we control semiconductor quantum dot spin qubits. Key qubit control schemes we previously developed individually using time-consuming hardware description languages are now easily implemented in one box.”
“Replacing three devices with one synchronized, orchestrated machine tremendously simplified lab workflow. Now our pulse sequences run in a fraction of the time of any other device combo. Plus, we can “talk” to the FPGA in human-speak, to run real-time calculations that were too complicated before! Along with the yoga-level.”
“The first time I was introduced to Quantum Machines, It surprised me how people were getting so excited about it. Only later did I realize, it was like explaining the value of a Laser before it existed, and all you knew are light bulbs. Today I truly believe that these systems will revolutionize our space.”
