谷歌又赢麻了!两位灵魂人物斩获2025诺贝尔物理学奖,“量子霸权”玩真的?
AI前线· 2025-10-08 02:54
整理 | 褚杏娟 当地时间 10 月 7 日,美国科学家 John Clarke、Michel H. Devoret 和 John M. Martinis 因"揭示量子物理实际应用的实验"荣获 2025 年诺贝尔物理学 奖,为下一代数字技术的发展奠定了基础。三人将分享 1100 万瑞典克朗(120 万美元)的奖金。 "我完全惊呆了。我从来没有想过这会成为诺贝尔奖的基础,"Clarke 通过电话向诺贝尔新闻发布会表示。他补充道,尽管他在 20 世纪 80 年代领导了这 三人的工作,但另外两人的贡献"是压倒性的"。Clarke 还表示,他们的研究得以开展,离不开 Anthony Leggett 与 Brian Josephson 的工作 —— 这两位 科学家为他们在超导电路隧穿效应方面的研究奠定了基础。Leggett 与 Josephson 均为往届诺贝尔奖得主。 "我现在用手机和你通话,我猜你也是一样。而手机之所以能正常工作,背后的原因之一就是所有这些研究的成果。"Clarke 表示。 Martinis 告诉《自然》杂志,他的妻子是在半夜(加州时间)得知这个消息的,但她决定暂时不叫醒他。"我六点前就醒了。然后我 ...

张瑜:黄金“狂想曲”——五种极端情形下的金价推演
一瑜中的· 2025-04-01 01:13
Core Viewpoint - The article emphasizes a bullish long-term outlook on gold, suggesting that the current global order is undergoing a significant transformation, akin to historical periods of major upheaval [2]. Group 1: Introduction and Background - Traditional pricing models for gold are failing to explain its recent price increases, as gold prices have reached new highs despite a strong dollar index [12]. - The article proposes a framework for extreme scenario analysis to assess gold's price elasticity and potential growth under various extreme conditions [15]. Group 2: Extreme Scenario Analysis Scenario 1: Emerging Market Accumulation - Emerging markets are increasingly concerned about the sustainability of U.S. debt, leading to a shift in foreign exchange reserves towards gold [4]. - If emerging markets raise their gold reserves to match developed markets' levels, demand could increase by 15,000 tons, consuming approximately 4-5 years of global gold production [4][19]. Scenario 2: Collapse of Crypto Assets - Bitcoin faces potential threats from quantum computing and policy changes, which could lead to a significant decline in its value [5]. - A hypothetical 20% drop in Bitcoin's market value could result in a massive influx of capital into gold, potentially exhausting the market's liquidity [5][29]. Scenario 3: Shift in Reserve Currency - The dominance of the U.S. dollar as a reserve currency may face structural challenges, with a projected decline in its share from 55% to 30% over the next decade [6]. - This shift could lead to an increase in global central bank gold purchases by approximately 30,000 tons, equivalent to 8-9 years of gold production [6][41]. Scenario 4: Escalation of Geopolitical Conflicts - In the event of global military conflicts, gold is expected to be revalued as a safe-haven asset, with historical precedents indicating significant price increases during such crises [7]. - The article posits that a 10% annual increase in global debt could lead to a substantial rise in gold prices, with a median estimate of $28,000 per ounce [7][52]. Scenario 5: Return to the Gold Standard - A return to a gold standard would fundamentally alter the monetary system, linking currency issuance to gold reserves and limiting excessive money printing [8]. - Under this scenario, the price of gold could reach a median estimate of $49,000 per ounce, driven by the need to back a significant amount of global debt with gold [8][58]. Group 3: Conclusion - The analysis suggests that gold may experience significant price increases in response to various extreme scenarios, highlighting its role as a hedge against systemic risks and currency instability [2][15].
