In the current quantum computing race, humanity seems trapped in "engineering against nature" attrition. Whether superconducting circuits or ion traps, we aim to maintain a few fragile "idealized" qubits through extreme isolation and refrigeration. This path, though logically clear, is like building sandcastles in a gale—engineering complexity grows exponentially.
What if we stop trying to control every qubit? This article proposes a new physical paradigm: leveraging matter's intrinsic complexity. We no longer pursue constructing isolated qubits but induce large-scale, intrinsically stable localized coherent states through a special all-carbon network material (¹²C). This belongs to Quantum Reservoir Computing (QRC)—it doesn't rely on precise instruction control but uses matter's own dynamical evolution to process information.
First step for quantum emergence: find an absolutely quiet "stage" for quantum states.
¹²C isotope purification: Natural carbon contains ~1.1% ¹³C; its nuclear spin causes magnetic fluctuations—main driver of quantum decoherence. This solution uses >99.9% purity ¹²C. With nuclear spin 0, this establishes "magnetically silent" background at sub-atomic scale, eliminating nuclear spin decoherence channel.
All-carbon self-bonding structure: Unlike traditional metal composites, this solution completely abandons metal solder. Through HPHT, nanodiamond (sp³) and in-situ graphitized (sp²) interface covalently bond. No electronic noise from free metal electrons; no interface thermal resistance—C-C covalent bonds achieve extreme phonon conduction; very high stability—sp³ rigidity and sp² flexibility interweave at atomic level.
Core driver comes from endogenous strain field at sp²–sp³ interface. During HPHT synthesis, due to significant elastic modulus difference between hybrid orbitals, GPa-level residual stress forms at interface. This extreme stress causes strong electron band distortion, potentially triggering: Band flattening: Enhanced electron correlation. Localized state enhancement: Nanoscale "electron dynamics islands". Phase stiffness: Under certain conditions, these islands may exhibit localized coherence. These coupled, randomly distributed but statistically uniform "islands" couple via sp² layers through quantum tunneling, building a vast 3D disordered coherent network.
Based on this material, we build not traditional CPU logic but a "physical reservoir": No precise control: We don't try to control every electron path but treat it as natural evolution field in high-dimensional Hilbert space. Compute logic: Input: excite complex dynamics in bulk via microwave perturbation, low-power optical pulse or flux modulation. Evolution: map input to high-dimensional state space via system nonlinear response, chaos boundary behavior, collective mode fluctuations. Emergence: like dropping stone in calm lake, we read complex superposition of ripples, not each water droplet's motion.
To maintain system's "holistic expression", this solution abandons single-point signal capture, using superconducting microwave resonant cavity coupling. When bulk undergoes dynamical evolution, macroscopic inductance or complex permeability fluctuates weakly. By detecting cavity frequency shift, we capture entire bulk's global statistical features. This readout has very high fault tolerance—even if local internal failure occurs, overall emergent pattern remains clear and stable.
Challenging pioneer concept—we will verify in three stages: Stage 1 (Material confirmation): Achieve stable metallic conductivity, confirm all-carbon skeleton thermal conductivity and mechanical stability. Stage 2 (Coherence tracing): "Decision point". Use STM/STS to find pseudogap signs, microwave spectroscopy for phase-related modes. Stage 3 (System identification): If localized coherence confirmed, establish dynamical model, formally conduct quantum reservoir computing system tests.
Must acknowledge this solution remains at physical hypothesis stage. Ultimate anchor for feasibility: does detectable phase degree of freedom exist in this all-carbon strain network?
Why is this concept crucial? It provides a new worldview: no longer trying to simulate intelligence by building "perfect machines" but inducing "complex matter" to produce emergence. If successful, ¹²C all-carbon network will not merely be ultra-hard, ultra-thermal-conductive material—it will become a physical carrier with "intuition". It is not only an experimental platform for quantum information but a cornerstone with sense of life toward humanity's carbon-based intelligent era.
