Ferroelectric devices are being used to create qubits for a new startup, Terra Quantum. The company is using its ferroelectrics-based technology to make a quantum computer that can be scaled up effectively. This will enable the field of cryptography and cybersecurity by creating more secure means of communication through complex encryption schemes relying on mathematical proofs based in part on principles from string theory.
A Swiss quantum computing company has just released what it claims is the largest funding round in the history of the quantum tech industry.
Terra Quantum announced on Thursday it extended its Series A funding to $75 million, which the company said would go toward strengthening its cryptographic and cybersecurity offerings.
The company also mentioned a recent breakthrough in ferroelectricity research it says will be key to miniaturizing electronics, along with its funding announcement.
A strong electric field can reverse the electric polarization of some materials, such as aluminum nitride. Despite Terra’s lack of detail in its announcement, the company says its technology can be used to build ferroelectric nanodot transistors and that it has been peer-reviewed.
“Terra Quantum researchers have described the design of a ferroelectric nanodots-based negative capacitance field-effect transistor in the Ninth Issue of Nature Partner Journal: Computational materials,” the journal noted.
A couple of Terra Quantum staff and three academics published an article titled: the ferroelectric field-effect transistor with negative capacitance in the 8th issue of that journal, though we couldn’t find the 9th issue.
The abstract goes:
By incorporating ferroelectric negative capacitance (NC) into the field-effect transistor (FET), we can break the Boltzmann tyranny, the fundamental limit on power dissipation. However, achieving the stable static negative capacitance in the non-transient, non-hysteretic regime remains a daunting task.
The design of the ferroelectric domain-based field-effect transistor with the stable reversible static negative capacitance is presented here.
Dielectric coatings on ferroelectric capacitors enable tuning of negative capacitance, thereby greatly improving field-effect transistors’ performance.
The transistors in this component could lead to ever-more tiny circuits and systems if this component works – transistors are the basic building blocks of today’s electronics.
The Future of Cryptography: What It Could Be, And Why You Should Be Excited
Terra claimed their discovery uncovered a key foundation for future technology, including terahertz-frequency-based electronics, non-invasive diagnostics, intra/interchip interconnects for more compact equipment, 6G hardware, and more. Terahertz signals are switched by tiny transistor gates to enable most of this technology.
In the supercomputing world, Terra starts going out on a limb by claiming that it can construct ferroelectric logical units with multi-bit quantum logic and that these will help it implement neuromorphic spiking neural networks that act like human brains. Terra believes it can use ferroelectric units as a model for qubits, based on their “multi-bit logic.”
The most basic building blocks (like a sustained qubit) of quantum computing are still the subject of experiments and research papers rather than new hardware. Quantum computing can also break traditional encryption with ease, but this remains firmly in the “maybe” category for now.
While this is the case, investment in quantum computing has continued to grow, with some predicting a growth rate of 50 percent a year by 2027.
Despite that, investment in quantum computing has continued to rise, with some predictions seeing the industry grow 50 percent each year from now until 2027. The US government has invested considerably in quantum computing, especially securing them, and venture capital firms have been giving billions away to startups in the hope their investment in quantum computing will be the one that strikes gold.
