PULSAR SERIES, FLEXIBLE QUBIT CONTROL WITH HIGH SIGNAL INTEGRITY ON YOUR DESKTOP

Many quantum setups do not require massive scaling of control or readout. For these setups (up to ~8 qubits), we provide standalone solutions; Pulsar QCM control module and the Pulsar QRM readout module.

Both equiped with the same QBLOX technology as found in our Cluster Series, the portable size of the Pulsar QCM and Pulsar QRM is ideal for quickly setting up experiments and replaces voluminous non-dedicated lab-equipment.

Learn how to shorten experimental run time (often by orders of magnitude) with advanced sequencing capabilities and parametrized operations. Even with its compact scale, Qblox Pulsar Series provide you with unleveled noise performance.

Expanding your experimental setup? Multiple Pulsars can be easily linked with our SYNQ protocol to ensure synchronized starting.

ideal for quickly setting up qubit experiments

  • Multiplexed control and readout up to 8 qubits per module.
  • Real-time (de)modulation and mixer corrections.
  • SYNQ starts multiple modules synchronously <<1 ns.
  • Real-time (de)modulation and mixer corrections.
  • Parameterized operations allow virtual Z-gates.
  • Low-latency feedback can be performed using the marker outputs/trigger inputs.
Pulsar Series QCM and QRM qubit control modules are the flexible choice for smaller experimental quantum setups up to ~8 qubits.

PULSAR QCM: DESKTOP QUBIT CONTROL MODULES IDEAL FOR SMALLER SETUPS

  • 4 analog output channels
  • 1 GSPS
  • 16 bit resolution
  • 5 Vpp output (50 Ω)
  • Ultralow noise and distortion
  • 4 binary markers out

A single Qubit Control Module (QCM) hosts 8 sequence processors for flexible multiplexed driving and tracking of up to 8 qubits (or other oscillators).

Advanced sequencer capabilities drastically speed up characterization experiments (Spectroscopy, Rabi, Chevron, Charge-stability diagrams) by avoiding repeated wave uploading and large overhead in software-controlled loops.

During quantum algorithms, it allows for instance arbitrary single-qubit control (phase, amplitude) from a single pulse pair. Qubit phases can be tracked in real time using the NCOs which accept virtual Z-gates through phase updates from the sequence processor.

  • Advanced distributed sequence processing
  • Multiplexed control of up to 8 qubits
  • Base-band operation or IQ-mode for single-sideband upconversion
  • Real-time modulation and mixer corrections
  • Real-time control: amplitude, offset, modulation frequency, modulation phase (virtual Z-gates)
  • Offset instructions allows constructing arbitrarily long (modulated) signals
  • Multiple Pulsars run fully synchronous via the SYNQ protocol
  • External instrument control by 4 marker outputs
Pulsar Series bring unlevelled noise performance and low-latency arbitrary control flow to your desktop. Get ready to connect via our Python API, QCoDeS or higher-level interfaces.

PULSAR QRM: QUBIT READOUT MODULE FOR MULTIPLEXED READOUT

  • 2 analog input channels
  • Variable 0.1 to 1 Vpp (50 Ω)
  • 2 analog output channels
  • 1 Vpp output (50 Ω)
  • 1 GSPS / 12 bit
  • 4 binary markers out

Combining inputs and outputs in one module makes reflectometry/transmission readout schemes ultimately convenient as the pulse and acquisition can be triggered from a single instruction.

Arbitrary pulse shapes and arbitrary integration functions can be uploaded to suppress crosstalk and optimize measurement efficiency under dynamic readout conditions.

Measurements on individual qubits can be multiplexed, but still their timing is completely independent, allowing an arbitrary scheduling of measurement operations.

alt
  • Distributed sequence processing even within one module
  • Multiplexed readout of up to 8 qubits per module
  • Arbitrarily long pulse and integration times can be achieved by construcing them from offset instructions

  • Real-time modulation with mixer corrections
  • Multiple Pulsars run fully synchronous via the SYNQ protocol
  • External instruments can be controlled from its 4 marker outputs
