Quantum States in a Nano-object Manipulated using a Mechanical System
August 28, 2015 | University of BaselEstimated reading time: 2 minutes
Scientists at the Swiss Nanoscience Institute at the University of Basel have used resonators made from single-crystalline diamonds to develop a novel device in which a quantum system is integrated into a mechanical oscillating system. For the first time, the researchers were able to show that this mechanical system can be used to coherently manipulate an electron spin embedded in the resonator – without external antennas or complex microelectronic structures. The results of this experimental study will be published in Nature Physics.
The oscillating resonator influences the electron spin in the nitrogen-vacancy centers (red arrows). Their spin can be efficiently read out by fluorescence microscopy.
In previous publications, the research team led by Georg H. Endress Professor Patrick Maletinsky described how resonators made from single-crystalline diamonds with individually embedded electrons are highly suited to addressing the spin of these electrons. These diamond resonators were modified in multiple instances so that a carbon atom from the diamond lattice was replaced with a nitrogen atom in their crystal lattices with a missing atom directly adjacent. In these “nitrogen-vacancy centers,” individual electrons are trapped. Their “spin” or intrinsic angular momentum is examined in this research.
When the resonator now begins to oscillate, strain develops in the diamond’s crystal structure. This, in turn, influences the spin of the electrons, which can indicate two possible directions (“up” or “down”) when measured. The direction of the spin can be detected with the aid of fluorescence spectroscopy.
Extremely fast spin oscillation
In this latest publication, the scientists have shaken the resonators in a way that allows them to induce a coherent oscillation of the coupled spin for the first time. This means that the spin of the electrons switches from up to down and vice versa in a controlled and rapid rhythm and that the scientists can control the spin status at any time. This spin oscillation is fast compared with the frequency of the resonator. It also protects the spin against harmful decoherence mechanisms.
It is conceivable that this diamond resonator could be applied to sensors – potentially in a highly sensitive way – because the oscillation of the resonator can be recorded via the altered spin. These new findings also allow the spin to be coherently rotated over a very long period of close to 100 microseconds, making the measurement more precise. Nitrogen-vacancy centers could potentially also be used to develop a quantum computer. In this case, the quick manipulation of its quantum states demonstrated in this work would be a decisive advantage.

Staying on Top of Signal Integrity Challenges
09/16/2025 | Andy Shaughnessy, Design007 MagazineOver the years, Kris Moyer has taught a variety of advanced PCB design classes, both online IPC courses and in-person classes at California State University-Sacramento, where he earned his degrees in electrical engineering. Much of his advanced curriculum focuses on signal integrity, so we asked Kris to discuss the trends he’s seeing in signal integrity today, the SI challenges facing PCB designers, and his go-to techniques for controlling or completely eliminating SI problems.
Integrating Uniplate PLBCu6 With the Digital Factory Suite
09/12/2025 | Giovanni Obino and Andreas Schatz, MKS' AtotechPrinted circuit board manufacturing is rapidly changing, driven by miniaturization, stringent reliability requirements, and growing pressure for sustainable production. Meeting these challenges requires more than incremental improvements; it demands a combination of precise equipment and real-time process intelligence. The pairing of Uniplate® PLBCu6 with the Digital Factory Suite (DFS) demonstrates how hardware and software can work together to create more responsive, resource-efficient manufacturing.
The Road to Reliability: Why EV Electronics Matter More Than Ever
09/16/2025 | Stanton Rak, SF Rak CompanyThe global transition to e-Mobility is redefining the design and reliability expectations of automotive electronics. Unlike their internal combustion engine (ICE) counterparts, EVs operate under "always-on" conditions and are subject to higher voltages, higher currents, and elevated thermal loads. These systems also incorporate exponentially more sensors, control units, and advanced power electronics, often tightly packed in thermally constrained spaces.
Smart Automation: Odd-form Assembly—Dedicated Insertion Equipment Matters
09/09/2025 | Josh Casper -- Column: Smart AutomationLarge, irregular, or mechanically unique parts, often referred to as odd-form components, have never truly disappeared from electronics manufacturing. While many in the industry have been pursuing miniaturization, faster placement speeds, and higher-density PCBs, certain market sectors are moving in the opposite direction.
Weaning the U.S. Military Off a Tablet Supply Chain That Leads to China
09/08/2025 | Jim Will, USPAETablet computers are essential to how our military fights, moves and sustains, but these devices are built on a fragile global supply chain with strong ties to China. Building domestic manufacturing to eliminate this vulnerability is feasible if we tap into the information and capabilities that already exist and create strong demand for tablets produced by trusted and assured sources.
