Dr. Pravir Malik is the founder and technologist of QIQuantum and the Forbes Technology Council group leader for Quantum Computing.
The quantum computing industry is undergoing an extraordinary phase of innovation. While often justified by practical motivations, such as breaking RSA encryption, solving complex optimization problems or transforming drug discovery, this dynamism may be propelled by something more profound. At its core, it signals a broader paradigm shift: a thinning veil between the invisible forces that underlie the universe and the visible forms they generate. We are approaching a moment where subjectivity and objectivity—traditionally seen as opposites—are beginning to converge, and quantum computing is emerging as a powerful medium for this synthesis.
The shape that matter or life assumes—whether atom, molecule or macromolecule—cannot be divorced from the subjective forces that, until now, have lingered in the background. These forces may not only determine form but also infuse it with meaning, influencing how the object behaves in and relates to the universe. Nature, it seems, computes through the interaction of such forms with light. This interaction establishes a persistent and inherently creative quantum computational process—one that is already a dance between the subjective and objective realms.
Remarkably, our technological advances are mirroring this deep structure. Breakthroughs in both atom-based and photonic quantum computing are accelerating, and their integration holds transformative potential. This convergence could usher in an era where computation is not just about the objective processing of data but also about extracting, shaping and operating on meaning itself.
We might refer to this next phase as meaning-based computation—a mode of quantum computing where the subjective dimension is not a byproduct but a core functional axis. It marks a profound leap: from solving equations to interpreting essence; from processing bits to navigating meaning.
Advancements In Neutral Atom And Photonic Quantum Computing
Neutral-atom quantum computing has rapidly evolved, showcasing profound capabilities. Platforms such as QuEra's neutral atom arrays exploit precise control of atoms trapped by optical tweezers, enabling sophisticated quantum operations. I recently hosted a Forbes event where we discussed QuEra's advancements. I'll only mention a few of the highlights below:
Photonic quantum computing, exemplified by Xanadu's advances, has made notable progress through continuous-variable (CV) quantum computing techniques. At a different Forbes event, Xanadu and its contributions were discussed. Here were some of the biggest takeaways:
Encoding Meaning In Quantum Systems
Using Quaternary Interpretation of Quantum Dynamics (QIQD), a framework detailed in a new Springer Nature book, Pioneering New Avenues in Quantum Technology, suggests how computation in meaning leveraging photonic and neutral atom computing becomes possible.
In QIQD, "meaning" can be encoded in continuous parameters of light interacting with atoms. According to QIQD, atoms embody fourfold or quaternary energetic imprints—quantifiable signatures defined by parameters such as frequency, amplitude, phase and polarization. Thus, an atom of silver holds a distinctly different quaternary imprint compared to one of gold. This conceptualization shifts computation from handling discrete states to manipulating specific, continuous, nuanced information.
In this QIQD framework, photonic systems, particularly those employing qumodes—a quantum mode of light, representing a continuous variable quantum system—emerge as superior computational mediums. Unlike qubits, which discretize information, qumodes inherently represent continuous variables, naturally aligning with QIQD's emphasis on continuous energetic imprints. Neutral atom arrays complement photonic computing. The stable coherence properties of neutral atoms facilitate the reliable extraction and preservation of atomic imprints. Furthermore, the versatility in arranging mixed-species arrays enhances the distinctiveness of these imprints, as different species possess unique resonant frequencies that enable highly selective and detailed probing. Dynamic rearrangement capabilities allow the exploration of new configurations and emergent functionalities.
Using Light And Atoms To Extract Meaning
Light extraction of these meanings in neutral atom arrays is envisioned to be precise and efficient. Tunable lasers, matched to the unique resonant frequencies of atomic species, selectively illuminate atoms, interacting with and extracting continuous-variable energetic imprints. These imprints manifest as specific modulations in the probing light's frequency, amplitude, phase and polarization. Techniques such as homodyne detection precisely measure these modulations, capturing the atomic "meanings" in the quantum states of qumodes. This captured information can then be manipulated, stored or transferred, facilitating advanced computational processes.
The practical implications of harnessing these deeper levels of quantum computation through the synergy of neutral atoms and photonics are transformative. Hypothetically, this could lead to combining signatures of elements known to be chemically incompatible. Helium and lithium signatures programmed into matter could revolutionize energy storage, superconductivity or advanced photonics. Similarly, new oxygen-fluorine or carbon-neon programmed matter could provide powerful oxidizers for propulsion or unique optical features crucial for future quantum computational technologies.
The Quantum Future Unveiled
The convergence of photonic quantum computing and neutral atom arrays—when interpreted through the lens of the QIQD—charts a bold and expansive trajectory for the future of quantum technology. It moves beyond the constraints of discrete-state architectures, ushering in a computational paradigm rooted in the continuous, expressive 'meanings' encoded in atomic energetic imprints. This emerging framework not only redefines how we compute but also how we understand the fabric of matter, energy and information itself, opening the door to a quantum future that is not just faster or more powerful but fundamentally more aware.
