Quantum Simulator Based on Molecular Spin Qudits

Simulation of the transverse Ising model

The use of d-level qudits instead of two-level qubits can largely increase the power of quantum logic for many applications, ranging from quantum simulations to quantum error correction. Magnetic molecules are ideal spin systems to realize these large-dimensional qudits. Indeed, their Hamiltonian can be engineered to an unparalleled extent and can yield a spectrum with many low-energy states. In particular, in the past decade, intense theoretical, experimental, and synthesis efforts have been devoted to develop quantum simulators based on molecular qubits and qudits. However, this remarkable potential is practically unexpressed, because no quantum simulation has ever been experimentally demonstrated with these systems.

Here, we show the first prototype quantum simulator based on an ensemble of molecular qudits and a radiofrequency broadband spectrometer. To demonstrate the operativity of the device, we have simulated quantum tunneling of the magnetization and the transverse-field Ising model, representative of two different classes of problems.

These results represent an important step toward the actual use of molecular spin qudits in quantum technologies.

Apparatus. The experimental apparatus for the characterization and control of the nuclear qudit has been specifically designed by combining the potentialities of the homemade broadband NMR spectrometer “HyReSpect” 64 with a fast state-of-the-art arbitrary waveform generator (Arb Rider AWG-5062D, hereafter AWG) from Active Technologies. The multifrequency pulse sequences for the coherent manipulation of the nuclear qudit were in fact generated by the AWG externally triggered by the spectrometer, while the spectrometer was devoted to the final state detection.
The characteristics of the experimental setup are particularly suitable for the present experiment: a flat response over a wide frequency span, very short dead times (<1.3 μs) to make echo-detection compatible with the qudit phase memory time, fast RF switching.

The AWG-5000 can generate sub-nanosecond pulses down to 230 ps reaching a voltage amplitude of 5Vpp on 50 ohm load and fast rise and fall time smaller than 110 ps. The pulses can be generated with any arbitrary shape giving the user the maximum of the flexibility in all the experiment conditions.

PSPL1P601 & PSPL1P602 Pulse Pattern Generator Replacement

Recently the most important T&M manufactures have discontinued a wide set of data generators, instrument extremely useful for digital logic & ICs characterization, functional and debugging testing, radar and receiver applications, signal integrity experiments.

The PSPL1P601 is a single-channel, 1.6 GHz pulse/pattern generator; the PSPL1P602 includes a second signal output channel. Both models have been recently discontinued.

The operational flexibility and pattern generation capability of the Pulse/Pattern Generators makes them suitable for use in many different applications, including simplified simulation of serial data patterns when testing devices to characterize their performance under suboptimal conditions.

The Pulse Pattern Generator family (PPG), also known as Serial Data Pattern Generator (SPG), is designed to generate a stream of binary information.
The Pulse Pattern Generator is available as an option in the Arbitrary Waveform  AWG-5000 Series.

The AWG-5000 True-Arb and PPG mode capabilities, allow you to emulate fast pulse and serial patterns up to 1.5 GHz, 230 ps of minimum width with an analog amplitude of 5 Vpp into 50 Ohm using the Single Ended model and 1.5 Vpp into 50 Ohm / 3Vpp into 100 Ohm through the Differential models.

All the pulse and pattern parameters can be controlled run-time, built-in PRBS sequences, modulation features and transition shaping features, are the perfect tools for Jitter emulation applications, semiconductor and signal integrity testing, PAM signal emulation and advanced research.

Moreover Active Technologies Pulse Pattern Generators are equipped with an extremely easy to use interface that takes full advantage of a 7″ capacitive touch-screen display: you can replace legacy products with the maximum flexibility control and a powerful analog frontend.
