QBLOX CONTROL SETUP FOR SUPERCONDUCTING QUBITS
A superconducting qubit Surface-17 setup for controlling flux-tunable transmons at a fixed frequency will be showcased, demonstrating:
- Speed up experiments with active reset: Shows how fast feedback enables active reset, speeding up qubit initialization compared to passive reset, including single and double threshold conditional resets.
- Improved two-qubit gate performance by removing distortions: Highlights the Qubit Control Module (QCM), combining slow and fast control in one source, eliminating the need for a bias tee and improving gate precision and speed.
- Faster to results with Quantify software: Demonstrates the intuitive software, simplifying experiments for single transmon tune-up.
- Multi-cluster synchronization (SYNQ): Illustrates Qblox's scalable solution with seamless daisy-chaining of mainframes, where the proprietary SYNQ protocol maintains synchronization to a 1-ns time grid for scalable, high-performance control next-gen quantum processors.
CLUSTER SETUP
With our modular approach, we can customize the electronics to meet your specific experimental requirements. To illustrate, we present a typical 5-qubit setup below:

QBLOX CONTROL SETUP FOR OPTICALLY ADDRESSABLE QUBITS
Color centers as Optically addressable qubits will be showcased, demonstrating:
- Achieve Precise Measurements: Integrated time tagging with the Qubit Timetag Module (QTM) enables g(2) photon autocorrelation to detect a single quantum emitter.
- Characterising the NV center qubit: Probing the qubit resonance frequency through Pulsed Optically Detected Magnetic Resonance (Pulsed ODMR) using the RF Qubit Control Module (QCM-RF II).
- Improve Qubit Stability: Dynamical decoupling techniques increase coherence time through optimized gate sequences.
- Implement Advanced Control: Photon-count based feedback coupled with a configurable truth table to facilitate entanglement heralding and Bell state measurements.

OVERVIEW
QPong is a fun, classic pong game reimagined and running on Qblox hardware.
- Experience a unique take on the classic game, engineered to run directly on Qblox setup.
- Visually, QPong utilizes X-Y mode on an oscilloscope, evoking the charm of vintage CRT displays.
- Powered by our assembly layer access Q1ASM, it demonstrates the broad applicability of Qblox's feedback mechanism to capture player input, from gaming to quantum experiments.
