• Published on bioRxiv, presenting a biophysical hypothesis that models triosephosphate isomerase (TIM), an enzyme essential for cellular glucose metabolism, as a quantum logic gate. • Predicted through a quantum mechanical model that SGLT2 inhibitors (SGLT2i), a diabetes treatment, reduce the probability of quantum decoherence in the TIM enzyme reaction. • Pioneering a new research frontier of quantum pharmacology by preventing the production of methylglyoxal, a cytotoxic byproduct, through the suppression of decoherence. [Quantum Biology Society] Groundbreaking biophysical research has been published revealing that an enzyme essential for cellular glucose metabolism (glycolysis) virtually operates like a quantum logic gate, the computational unit of a quantum computer. Going beyond classical biochemistry, this is a milestone achievement interpreting the human protective mechanisms of metabolic disease treatments from the perspective of subatomic quantum information processing. A paper titled "Triosephosphate Isomerase as a Quantum Logic Gate: Could quantum decoherence be toxic?" was released on the preprint repository bioRxiv. A joint research team of Daniele Romanello, a physician in Internal Medicine at Ospedale San Pietro Fatebenefratelli in Rome, Italy, and Andrea Romanello from the Department of Information Engineering at Sapienza University of Rome proposed this innovative quantum medical model. ■ Enzyme Catalysis Interpreted as Quantum Computation The researchers focused on the catalytic process of triosephosphate isomerase (TIM), a key enzyme in glycolysis, converting dihydroxyacetone phosphate (DHAP) to glyceraldehyde-3-phosphate (G3P). Instead of viewing this process merely as a classical "lock-and-key" model where specific molecular structures fit together, they remodeled it as a highly advanced quantum computational workflow involving precise proton transfer. This implies that enzymes in vivo act as logic circuits that autonomously control quantum states to derive specific biochemical outcomes. ■ SGLT2 Inhibitors Protect Cells by Preventing Quantum Decoherence What is even more interesting is that this quantum model interpreted the hidden human protective effects of sodium-glucose co-transporter 2 inhibitors (SGLT2i), which are widely prescribed as treatments for heart failure and diabetes. According to the model's predictions, if quantum decoherence occurs—where the enzyme loses its quantum state due to interference from the external environment during the metabolic process—it produces methylglyoxal, a toxic byproduct that destroys cells and strongly accelerates aging. As a result of the researchers' analysis, SGLT2i drugs were found to significantly reduce the probability of quantum decoherence in this TIM enzyme reaction. In other words, by suppressing the noise in the intracellular quantum computation process, the drug dramatically lowers the accumulation of the highly toxic substance methylglyoxal, ultimately exerting a powerful organ-protective effect. ■ The Prelude to the Era of Quantum Pharmacology This study holds great significance in that it reinterprets the pathogenesis of diseases and the mechanism of drug action beyond molecular chemical bonds, from the perspective of quantum coherence and dynamics. Experts anticipate that this approach will serve as an excellent starting point for quantum pharmacology, bringing a fundamental paradigm shift to the design of next-generation drugs for treating metabolic syndrome and degenerative diseases.

Some of lattice-gauge-theory models, in particular gauge-Higgs model (GHM), can be regarded and work as a subsystem code. This work studies the effect of local-gauge-symmetric decoherence on the GHM from the perspective of the subsystem code. We clarify the global phase diagram of the subsystem code. In particular, the decoherence induces an unconventional critical mixed state, where the logical information is preserved but the rest of the system exhibits mixed state criticality. For a fixed point, the decohered subsystem code is understood by the ``gauging out" prescription. By mapping the GHM to the toric code subject to decoherence, we can understand the properties of the subsystem code. We further discuss and investigate the robustness of the logical space of the subsystem code. Although this kind of subsystem code can be produced by using any bulk mixed state in the GHM, its robustness is a subtle problem due to the mixed critical gauge qubits. We consider some specific unitary for examining the robustness of the stored quantum information. For dynamical unitary perturbations described by interactions between the logical qubit and gauge qubits, the deformation of the subsystem code drastically depends on the initial mixed state of the gauge qubits.

• Raised the hypothesis that 'TIM', a pivotal enzyme in cellular glycolysis, functions as a 'quantum logic gate' beyond a simple chemical catalyst. • Elucidated that upon the occurrence of quantum decoherence, methylglyoxal, a toxic substance causing diabetic complications, is produced. • Reinterpreted the root cause of metabolic diseases as a 'failure of quantum interference', and demonstrated the protective effects of SGLT2 inhibitors through a quantum model. [Quantum Biology Society] Groundbreaking research results have emerged suggesting that metabolic enzymes, which generate energy in our bodies, operate not merely as simple chemicals, but like 'quantum logic gates', the computational units of quantum computers. Recently, a paper titled "Triosephosphate Isomerase as a Quantum Logic Gate: Could quantum decoherence be toxic?" was published on bioRxiv, a preprint repository for biology. This study is drawing extraordinary attention from the medical community by reinterpreting the pathogenesis of diseases from a quantum mechanical perspective, going beyond classical biochemistry. ■ A Key Enzyme in Life Phenomena Operates as a 'Quantum Logic Gate' The research team focused on the operational mechanism of 'triosephosphate isomerase (TIM)', a pivotal enzyme in cellular glycolysis that breaks down glucose into energy. The researchers modeled the precise proton transfer process occurring within the enzyme as a 'quantum tunneling' action rather than a simple chemical catalytic reaction. This is an unconventional hypothesis that the TIM enzyme functions like a 'quantum logic gate', the fundamental unit of a quantum computer, to control the conversion of substances with extreme precision. ■ Quantum Errors (Decoherence) Create 'Toxicity' The most surprising discovery is what happens when inefficiencies arise due to the so-called 'quantum decoherence' phenomenon during this quantum tunneling process. The study showed that when an error occurs in the computation (catalysis) as the quantum state breaks down, a fatal toxic byproduct called 'methylglyoxal' is produced instead of normal metabolites, inducing the formation of advanced glycation end products (AGEs) that cause diabetic complications. In other words, a 'quantum mechanical malfunction' (failure of quantum tunneling) of metabolic enzymes in cells can be the direct cause of metabolic disease complications. ■ The Efficacy of the Diabetes Drug 'SGLT2 Inhibitors' Proven by a Quantum Model... A New Paradigm in Drug Development Furthermore, the research team developed a mathematical quantum model of how 'SGLT2 inhibitors', a widely used diabetes treatment, protect the body. As a result of simulation analysis through a Python script, it was confirmed that this drug exerts a protective effect on vascular and renal cells by lowering the probability of the formation of the toxic intermediate (methylglyoxal). This approach is highly significant in that it reinterpreted the root cause of metabolic diseases, including diabetes, as a problem at the level of 'quantum interference' rather than a simple chemical imbalance. This research, which identified the causes of diseases from a quantum mechanical perspective and theoretically proved the efficacy of drugs, is expected to provide a strong foundation for the development of new metabolic disease drugs with novel mechanisms that fundamentally block the generation of toxic byproducts in the future.
